General Safety Precautions
Materials testing systems are potentially hazardous.
Materials testing involves inherent hazards from high forces, rapid motions, and
stored energy. You must be aware of all moving and operating components in
the testing system that are potentially hazardous, particularly force actuators or
a moving crosshead.
Carefully read all relevant manuals and observe all Warnings and Cautions. The
term Warning is used where a hazard may lead to injury or death. The term
Caution is used where a hazard may lead to damage to equipment or to loss of
data.
Instron products, to the best of its knowledge, comply with various national and
international safety standards, in as much as they apply to materials and
structural testing. We certify that our products comply with all relevant EU
directives (CE mark).
Because of the wide range of applications with which our instruments are used,
and over which we have no control, additional protection devices and operating
procedures may be necessary due to specific accident prevention regulations,
safety regulations, further EEA directives or locally valid regulations. The extent
of our delivery regarding protective devices is defined in your initial sales
quotation. We are thus free of liability in this respect.
At your request, we will gladly provide advice and quotations for additional
safety devices such as protective shielding, warning signs or methods of
restricting access to the equipment.
The following pages detail various general warnings that you must heed at all
times while using materials testing equipment. You will find more specific
Warnings and Cautions in the text whenever a potential hazard exists.
Your best safety precautions are to gain a thorough understanding of the
equipment by reading your instruction manuals and to always use good
judgement.
It is our strong recommendation that you should carry out your own product
safety risk assessment.
Hazard - Press the Emergency Stop button whenever you consider that an
unsafe condition exists.
The Emergency Stop button removes hydraulic power or electrical drive from the
testing system and brings the hazardous elements of the system to a stop as
quickly as possible. It does not isolate the system from electrical power, other
means are provided to disconnect the electrical supply. Whenever you consider
that safety may be compromised, stop the test using the Emergency Stop
button. Investigate and resolve the situation that caused the use of the
Emergency Stop button before you reset it.
Flying Debris Hazard - Make sure that test specimens are installed correctly
in grips or fixtures in order to eliminate stresses that can cause breakage of
grip jaws or fixture components.
Incorrect installation of test specimens creates stresses in grip jaws or fixture
components that can result in breakage of these components. The high
energies involved can cause the broken parts to be projected forcefully some
distance from the test area. Install specimens in the center of the grip jaws in
line with the load path. Insert specimens into the jaws by at least the amount
recommended in your grip documentation. This amount can vary between 66%
to 100% insertion depth; refer to supplied instructions for your specific grips.
Use any centering and alignment devices provided.
Hazard - Protect electrical cables from damage and inadvertent
disconnection.
The loss of controlling and feedback signals that can result from a disconnected
or damaged cable causes an open loop condition that may drive the actuator or
crosshead rapidly to its extremes of motion. Protect all electrical cables,
particularly transducer cables, from damage. Never route cables across the
floor without protection, nor suspend cables overhead under excessive strain.
Use padding to avoid chafing where cables are routed around corners or
through wall openings.

High/Low Temperature Hazard - Wear protective clothing when handling
equipment at extremes of temperature.
Materials testing is often carried out at non-ambient temperatures using ovens,
furnaces or cryogenic chambers. Extreme temperature means an operating
temperature exceeding 60 °C (140 °F) or below 0 °C (32 °F). You must use
protective clothing, such as gloves, when handling equipment at these
temperatures. Display a warning notice concerning low or high temperature
operation whenever temperature control equipment is in use. You should note
that the hazard from extreme temperature can extend beyond the immediate
area of the test.
Crush Hazard - Take care when installing or removing a specimen,
assembly, structure, or load string component.
Installation or removal of a specimen, assembly, structure, or load string
component involves working inside the hazard area between the grips or
fixtures. When working in this area, ensure that other personnel cannot operate
any of the system controls. Keep clear of the jaws of a grip or fixture at all times.
Keep clear of the hazard area between the grips or fixtures during actuator or
crosshead movement. Ensure that all actuator or crosshead movements
necessary for installation or removal are slow and, where possible, at a low
force setting.
Hazard - Do not place a testing system off-line from computer control
without first ensuring that no actuator or crosshead movement will occur
upon transfer to manual control.
The actuator or crosshead will immediately respond to manual control settings
when the system is placed off-line from computer control. Before transferring to
manual control, make sure that the control settings are such that unexpected
actuator or crosshead movement cannot occur.
Robotic Motion Hazard - Keep clear of the operating envelope of a robotic
device unless the device is de-activated.
The robot in an automated testing system presents a hazard because its
movements are hard to predict. The robot can go instantly from a waiting state
to high speed operation in several axes of motion. During system operation,
keep away from the operating envelope of the robot. De-activate the robot
before entering the envelope for any purpose, such as reloading the specimen
magazine.
Warnings
Hazard - Set the appropriate limits before performing loop tuning or running
waveforms or tests.
Operational limits are included within your testing system to suspend motion or
shut off the system when upper and/or lower bounds of actuator or crosshead
travel, or force or strain, are reached during testing. Correct setting of
operational limits by the operator, prior to testing, will reduce the risk of damage
to test article and system and associated hazard to the operator.
Electrical Hazard - Disconnect the electrical power supply before removing
the covers to electrical equipment.
Disconnect equipment from the electrical power supply before removing any
electrical safety covers or replacing fuses. Do not reconnect the power source
while the covers are removed. Refit covers as soon as possible.
Rotating Machinery Hazard - Disconnect power supplies before removing
the covers to rotating machinery.
Disconnect equipment from all power supplies before removing any cover which
gives access to rotating machinery. Do not reconnect any power supply while
the covers are removed unless you are specifically instructed to do so in the
manual. If the equipment needs to be operated to perform maintenance tasks
with the covers removed, ensure that all loose clothing, long hair, etc. is tied
back. Refit covers as soon as possible.
Hazard - Shut down the hydraulic power supply and discharge hydraulic
pressure before disconnection of any hydraulic fluid coupling.
Do not disconnect any hydraulic coupling without first shutting down the
hydraulic power supply and discharging stored pressure to zero. Tie down or
otherwise secure all pressurized hoses to prevent movement during system
operation and to prevent the hose from whipping about in the event of a
rupture.
Hazard - Shut off the supply of compressed gas and discharge residual gas
pressure before you disconnect any compressed gas coupling.
Do not release gas connections without first disconnecting the gas supply and
discharging any residual pressure to zero.

Explosion Hazard - Wear eye protection and use protective shields or
screens whenever any possibility exists of a hazard from the failure of a
specimen, assembly or structure under test.
Wear eye protection and use protective shields or screens whenever a risk of
injury to operators and observers exists from the failure of a test specimen,
assembly or structure, particularly where explosive disintegration may occur.
Due to the wide range of specimen materials, assemblies or structures that may
be tested, any hazard resulting from the failure of a test specimen, assembly or
structure is entirely the responsibility of the owner and the user of the
equipment.
Hazard - Ensure components of the load string are correctly pre-loaded to
minimize the risk of fatigue failure.
Dynamic systems, especially where load reversals through zero are occurring,
are at risk of fatigue cracks developing if components of the load string are not
correctly pre-loaded to one another. Apply the specified torque to all load string
fasteners and the correct setting to wedge washers or spiral washers. Visually
inspect highly stressed components such as grips and threaded adapters prior
to every fatigue test for signs of wear or fatigue damage.

System Description and Terminology
Product Support: www.instron.com
Principle of Operation
The system communicates primarily through the controller. The controller contains
sensor conditioning cards for the system transducers and transfers data between the
transducers and the computer. The controller also communicates with the load frame
via a Safety Monitoring Board (SMB) via a Break Out Board (BOB) inside the load frame.
The Break Out Board links all the electrical components of the frame together.
Hardware Controls
The hardware controls consist of:
• Emergency stop button - to be used whenever you need to stop the crosshead
immediately because an unsafe condition exists.
Table 1. Testing System Components
Component
Description
Load Frame
The load frame comprises a base, one or two columns, a moving crosshead,
and a top plate. It is a high stiffness support structure against which the test
forces react.
Each column comprises a guide column and a ballscrew. The crosshead is
mounted on both the guide column and the ballscrew. Rotation of the
ballscrew drives the crosshead up or down while the guide column provides
stability.
Controller
The hardware that controls the frame and any ancillary equipment connected
to the testing system. The controller panel contains all the connectors for load
cells, extensometers and any other sensors that are required for testing.
Frame Control Panel
This panel holds all of the controls and indicators for the testing system.
Load String
Comprises all of the components that you install between the moving
crosshead and the load frame base (or fixed crosshead). Typically this involves
a load cell, a set of grips, any adapters that are required to connect the
components, and the specimen to be tested.
Typically, you mount a load cell on the crosshead, then a pair of grips or
fixtures on the load cell and frame base. The grips or fixtures secure the
specimen and when you start a test the crosshead moves up or down applying
a tensile or compressive load to the specimen. The load cell converts this load
into an electrical signal that the software measures and displays.
Bluehill® Software
Instron® testing software that controls the testing system, running tests and
analyzing test data to produce test results.
Specimen
A single piece of material to be tested.
• Limit stops - these must be set before each test session to protect the operator and
load string components against unexpected crosshead movement.
• Frame control panel - holds all the controls and indicators for the testing system.
Software
Control of the testing system is carried out via Instron Bluehill® software. Setting test
parameters, operating the system, and collecting test data is done through the software
program.
System Safety and Information Labeling
Table 3 on page 20 explains the meanings of any safety and information labels that
may be attached to any part of the testing system.
Table 2. Software Terminology
Term
Description
Test Method
In Bluehill® software, a test method is a file that contains a set of defined
parameters that the system uses to run tests, analyze the test data, and
produce calculated results.
Sample
A group of material specimens, whose properties are studied and
compared to gain statistical or quality assurance information. For
example, you could take a specimen from different parts of a single
manufacturing run of a material to form a sample of the material. The
sample is then representative of the complete run and you can test it to
ensure that the material quality has remained stable over the complete
run. You perform the same test on each specimen in a sample.

Residual risks
The equipment described in this documentation is designed with features to reduce the
risk of injury to an operator. There are, however, always residual risks in the use of this
equipment, influenced by:
• the test application
• the design of the test method or procedure
• the jog, return and test speeds used
• the type of specimen being tested
• the size of the specimen being tested
• the design of grips and test fixtures
• the experience of the operator using the equipment
It is our strong recommendation, therefore, that you carry out your own risk assessment
for your particular equipment setup and testing application.
Each of the following sections describes a specific hazard zone of the testing system
and lists the most common risks for testing using this equipment. Use the information in
the following sections, together with the instructions in the remainder of this manual, to
conduct your own risk assessment.
Chapter: Risk reduction and safe use
26
M10-17318-EN
Rapid crosshead motion
Warning
Crush hazard to fingers or hands.
This hazard relates to grips and fixtures coming together as a result of rapid crosshead
motion, crushing hands or fingers.
For example, an operator inadvertently commands the system to jog or return while their
hands are in test area. This may also happen if the operator, in an attempt to be more
efficient, reaches in to remove broken specimen pieces while simultaneously returning
the crosshead to zero displacement.
Recommendations
In all situations:
• Set up test methods so that operators do not need to have their hands in the space
between fixtures while the crosshead is moving.
• Use the Operator Protection feature in Bluehill® software. This uses a reduced jog
speed (default 600 mm/min) during set up and you can set a lower jog speed if your
risk assessment requires it.
• Set appropriate travel limits every time you change the grips and adjust the
crosshead.
In addition, if the gap between grips and fixtures is less than 50 mm:
Product Support: www.instron.com
• Use a specimen insertion tool and other appropriate equipment and practices to
keep fingers out of the space between the fixtures.
In addition, if the gap between grips and fixtures is less than 25 mm:
• Use a specimen insertion tool to keep fingers out of the space between the fixtures.
• Use an interlocked shield to limit or disallow motion when the shield door is open.
When the space is less than 25mm, the crush hazard is very significant, so this is
the best option.
Chapter: Risk reduction and safe use
28
M10-17318-EN
Pinching fingers between grip jaw faces
Warning
Pinch hazard to fingers.
This hazard relates to grip jaws closing quickly, pinching fingers.
Recommendations
For 2712 Series pneumatic grips:
• In the documentation supplied with the grips, read and follow the safety
recommendations for installing a specimen.
• Use the Operator Protection feature in Bluehill® software. This uses a reduced initial
grip pressure (default 15 psi) during set up and you can set a lower initial grip
pressure if your risk assessment requires it.
Refer to “Pneumatic Grips” on page 66 for more details.
• Use jaw face shields.
• Use the thumb screw knobs on the sides of the grip (2712-04x grips only) to reduce
the jaw face gap to the smallest practical gap for your specimens.
Correct:
Product Support: www.instron.com
Incorrect:
Impact of debris from breaking specimens
Warning
Hazard from flying debris.
This hazard relates to brittle or composite specimens that can explode when they break.
Recommendations
For less dangerous debris (specimen dust or fibers, for example):
• Use personal protection equipment (for example safety glasses).
For more dangerous projectile debris (brittle composite specimens, for example):
• Use an interlocked shield.
Chapter: Risk reduction and safe use

M10-17318-EN
Operator Protection Overview
The majority of hazards for operating materials testing systems are associated with:
• rapid movement of the crosshead causing crush injuries
• rapid closing of pneumatic grips causing pinch injuries
Operator Protection in Bluehill® provides a mechanism that lets you limit crosshead jog
speed and reduce grip closing pressure while you are setting up a test.
The default conditions during test set up are:
• crosshead jog speed reduced to a maximum of 600 mm/min, and can be set lower
if your risk assessment requires it
• grip closing pressure reduced to a default of 15 psi, and can be set lower if your risk
assessment requires it.
Refer to “How Operator Protection works with grips” on page 66 for more
details.
Operator Protection lets an Administrator configure the testing system to be consistent
with the risk assessment for that system.
Access to the controls for Operator Protection is password protected. If you have
Administrator rights you can modify Operator Protection in the Admin tab in Bluehill®.

“Testing a sample” on page 91. This section contains two procedures, one for
systems using an interlock and one for systems without an interlock.
Jog at High Speed
Under normal conditions, in SET UP mode, jog speed is limited to 600 mm/min or less.
There may be situations, such as moving the crosshead into position at the start of a
testing session, where this low speed in inconvenient.
Jogging at high speed involves more risk so the process involves pressing both the
UNLOCK and JOG buttons at the same time, as follows:
Additional notes:
• Although you must press the UNLOCK and JOG buttons together to start the jog at
full speed, you can release the UNLOCK button once the crosshead starts to move.
The crosshead ramps up to full speed and continues to move while you are pressing
the JOG button.

Operator Protection Controls
If you have Administrator rights, you can make changes to the Operator Protection
settings, via Admin > Frame > Operator Protection.
For more details on the operation of these software controls, refer to the Bluehill®
online help and reference.
Operator Protection options define the restrictions on the system when it is in SET UP
mode.
Control
Description
Jog rate
Sets the restricted speed of the crosshead when the
system is in SET UP mode. Default setting is 600 mm/min,
which is also the maximum permitted.
If the maximum speed of the crosshead is less than
600 mm/min, then the restricted speed is limited to the
maximum speed of the frame.
Initial grip air pressure
Sets the maximum grip pressure allowed when the system
is in SET UP mode.
Allows the operator to close the grips on the specimen with
sufficient pressure to hold the specimen in place but
reduces the risk of injury from pinching.
Override point of control
Default is disabled, which means that the primary point of
control for the system is at the load frame. The operator
must use the buttons on the frame to start a test or
position the crosshead.
When this option is enabled, the system can be configured
to use the software to initiate these actions.
Override point of control -
Start test and return
Default is Frame Controls, i.e. start test and return using
the buttons on the frame.
Only choose Remote if you are using an interlock
accessory. The interlock automatically transitions the
system to CAUTION mode when the interlock is closed. If
there is no interlock, you must press the UNLOCK button
to transition to CAUTION mode.

Pneumatic grips
Enables and disables pneumatic grips connected to the
testing system with the integrated air kit.
Grip control (when pneumatic
grips are enabled)
Default is Footswitch. You close both grips using the
integrated air kit and foot switch.
Toggle switch lets you use the toggle switches on the
grips with the integrated air kit. The footswitch is disabled
when you choose this.
Remote lets you control the grips via a software program
operating through the API.
Upper footswitch/lower remote applies only if your test
method includes pretension. Upper grip closes with the
foot switch and the lower grip closes automatically after
the specified load threshold is achieved.
Behavior when the interlock
is tripped
If the testing system includes an accessory with an
interlock, then Operator Protection defines the behavior
of the frame when the interlock is tripped. For example,
when an interlocked door is opened and the operator has
access to the test area.
Disable frame - the frame is disabled when the interlock
is tripped. This is the recommended setting as it is the
safest.1
Allow limited motion - the frame remains enabled when
the interlock is tripped. This allows an operator access to
the test area while allowing limited crosshead movement
as specified in Operator Protection.
Although this option can facilitate installing a specimen or
removing an extensometer during a test, it also increases
the risk of injury. You should perform a risk assessment
before selecting this option.
1. If you choose this option, be aware that the operation of pneumatic grips is also disabled. If
you want no crosshead motion when the interlock is tripped but need pneumatic grips to
function, select Allow limited motion and set Jog rate to 0 mm/min.

Pneumatic Grips
Table 7 on page 66 lists the pneumatic grips recommended for use with these testing
systems, combined with the optional integrated air kit and footswitch. They utilize the
grip control features of Operator Protection including reduced initial grip pressure, which
reduces the speed and force of closing while setting up a test, thus reducing the risk of
injury.
Warning
Always disable the frame before installing or changing pneumatic grips.
When the frame is enabled, the integrated air kit is pressurized. If you attach a grip to
the system in this state, the grip could close.
Other pneumatic grips can be used with the system, including operation with the
integrated air kit and footswitch, but they may not be designed to utilize the full range of
features of Operator Protection. Contact Instron® Service for advice.
How Operator Protection works with grips
When in SET UP mode, pneumatic grips close at a reduced initial grip pressure. The
lower the pressure, the lower the force and speed at which the grips close. You should
therefore set this speed to the minimum required to close the grips and grip the
specimen within a reasonable time, but taking into account that even low pressures can
cause injury.
The default value is 15 psi. The following table lists recommended initial grip pressures
for the pneumatic grips listed in Table 7 on page 66:
Table 7. Recommended pneumatic grips

250 N
2712-051
50 N1
1. These low capacity grips do not include the toggle switch.
Product Support: www.instron.com
Minimum pressure may be slightly higher or lower for any given grip due to age,
environmental conditions and use.
Warning
Be aware that even at these recommended initial grip pressures, the force exerted
by the closing grips can cause injury.
For example, a 10 kN grip closing at the default initial pressure of 15 psi exerts a
minimum force of 4kN (900 lbf). The same grip closing at 7 psi exerts a minimum force
of 1.9kN (420 lbf), still a significant force that can cause injury.
Warning
Be aware also that setting initial grip pressure too low may result in the grip not
closing completely at the initial grip pressure. This may cause a hazard when the
grips transition to full pressure.
If the grips do not close completely at the initial pressure, they will close at full force
when the grips transition to full pressure.
Warning
If the grips feature an air inlet flow adjustment control (see below), make sure that
the flow adjustment is set to fully open (screw fully counterclockwise).
Do not use the air inlet flow adjustment control to reduce air flow as you risk
transitioning from initial pressure to full pressure before the grips have closed. If the

grips do not close completely at the initial pressure, they will close at full force when
the grips transition to full pressure.
In addition to the hazard caused by reducing the air flow, operation of the air inlet flow
adjustment control can result in an inaccurate grip pressure reading which may disable
the frame.
You can remove the air inlet flow adjustment control and connect the 1/8” NPT quick
disconnect directly to the grip or via a 1/8” NPT right angle male to female adapter, as
shown below.
Operate grips using footswitch
The recommended pneumatic grip configuration is one of the grips listed in Table 7 on
page 66 combined with the integrated air kit and footswitch.
Product Support: www.instron.com
If for any reason you have to disconnect the footswitch from the frame controller, you
must cycle power on the frame to re-establish communication between the footswitch
and the frame.
The operation of this configuration with Operator Protection is described in “Operator
Protection using the footswitch” on page 69.
Caution
The pneumatic-only, single pedal footswitch (Cat. no. 2701-004) is NOT suitable for
use with these systems.
Operator Protection using the footswitch
The point of control for grips in the Operator Protection control dialog must be set to
Footswitch.
The footswitch operates as follows:
• tap right pedal once, closes grip connected to port 1 (typically the top grip)
• tap right pedal again, closes grip connected to port 2 (typically the bottom grip)
• tap left pedal once, opens both grips
The footswitch integrates with Operator Protection as follows:
• in SET UP mode, you can open and close the grips
• in CAUTION mode, you can open the grips
• in DISABLED or TESTING mode, the footswitch does not operate
Warning
If your grips have toggle switches installed, do not use them when the point of
control for grips is set to Footswitch.
If you intend to always use the footswitch, you should replace the toggle switches on the
grips with the blanking plugs provided with the grips in the ancillary parts kit.
1.
Starting with the system in DISABLED mode, press the UNLOCK button.
The system moves to SET UP mode.
2.
Operate the system in SET UP mode and install the specimen using the footswitch to
open and close the grips at the initial pressure set in the software.
3.
Press the UNLOCK button to transition to CAUTION mode.
The grips pressurize to full pressure.

grips continue at full pressure until you run a test or release the grips.
The system transitions to TESTING mode.
5.
Stop the test, or the test ends.
The system reverts to SET UP mode but the grips are maintained at full pressure
until you open them using the footswitch.
Warning
Do not operate the toggle switches when the testing system is in TESTING mode and
the grips are pressurized to full pressure.The system may detect an error and disable
the frame.
You must not operate the toggle switches when the grips are at full pressure. The grips
will open but when you use the toggle switch again to close the grips, the grips will close
at full pressure and the system may detect an error and disable the frame.
You may start a test with one grip closed if desired. If you move to CAUTION mode after
closing one grip, you cannot close the second grip, even if you transition back to SET UP
mode. You must use the footswitch to open the first grip in order to proceed.
Operate grips using toggle switches
The recommended pneumatic grip configuration is one of the grips listed in Table 7 on
page 66 combined with the integrated air kit and footswitch.
If you are using the integrated air kit but prefer to use toggle switches on the grips
instead of a footswitch there are some differences in the operation of the grips that you
should be aware of:
• Grips maintain full pressure during TESTING mode only. At the end of a test, when
the system reverts to SET UP mode, the grip pressure reduces to the initial grip
pressure. This may cause problems if the specimen has stored energy which could
cause the specimen to slip out of the grips. If that is a concern, you should use a
footswitch to run your tests.
• You must not operate the toggle switches when the grips are at full pressure. The
grips will open but when you use the toggle switch again to close the grips, the grips
will close at full pressure and the system may detect an error and disable the frame.
The operation of this configuration with Operator Protection is described in “Operator
Protection using the toggle switches” on page 71.
Product Support: www.instron.com
Operator Protection using the toggle switches
The point of control for grips in the Operator Protection control dialog must be set to
Toggle switch.
If you have a footswitch connected to the system, it will not operate.
Warning
Make sure that the toggle switches are in the open position.
If the toggle switches are in the closed position, the grips will close immediately
when the system transitions to SET UP mode.
1.
Starting with the system in DISABLED mode, press the UNLOCK button.
The software displays a message, warning you to make sure that the toggle
switches are in the open position.
2.
Press the UNLOCK button again to transition to SET UP mode.
3.
Operate the system in SET UP mode and install the specimen using the toggle
switches to open and close the grips at the initial pressure set in the software.
4.
Press the UNLOCK button to transition to CAUTION mode. The grips are maintained
at the initial grip pressure.
5.
Within 2 seconds, press the START TEST button to start the test.
The system transitions to TESTING mode and the grips pressurize to full pressure.
6.
Stop the test, or the test ends.
The system reverts to SET UP mode and the grip pressure returns to the initial grip
pressure.
Chapter: Function of controls
72
M10-17318-EN
Caution
If your test ends and the specimen has stored energy, e.g. the specimen did not break,
the specimen may slip out of the grips when the grip pressure reduces at the end of the
test.
If this could be an issue, it is recommended that you set the point of control for grips to
Footswitch and use a footswitch for your tests. When using a footswitch, pneumatic
grips remain at full pressure after the test ends until you release them using the
footswitch.
Warning
Do not operate the toggle switches when the testing system is in TESTING mode and
the grips are pressurized to full pressure.The system may detect an error and disable
the frame.
You must not operate the toggle switches when the grips are at full pressure. The grips
will open but when you use the toggle switch again to close the grips, the grips will close
at full pressure and the system may detect an error and disable the frame.
Grips not in use
There may be situations where you want to remove the grips from the load string,
placing them on a bench alongside the system perhaps while you perform different
types of tests. Be aware that if the point of control for grips is set to Toggle, the grips
could present a hazard.
Warning
If you remove the pneumatic grips from the load string but do not disconnect them
from the integrated air kit, you should disablethe grips in the Operator Protection
controls in the software.
If the point of control for grips in the software is set to Toggle, and you remove them
from the load string without disconnecting them from the integrated air kit, the grips will
close at initial pressure and cycle between full pressure and initial pressure as you
continue your testing.

The load string consists of all the hardware components between the crosshead and the
base of the testing machine. It includes the load cell, grips, the specimen and any
adapters that let you connect any of these components together.
Instron® Service sets up the testing machine during installation, but you may need to
change one or more of these components for different types of testing.
When creating a load string, keep in mind the maximum capacity for all the components
making up the load string. The expected test load should not exceedthe maximum
capacity of any load string components including, but not limited to:
• load frame
• load cell
• adapters
• grips or fixtures
Select a load cell
If you know the approximate tensile or compressive strength of the material that you are
testing, use these guidelines to choose a load cell:
Chapter: Assemble the load string
74
M10-17318-EN
• Make sure that the load cell is verified for the range of force that you anticipate for
your testing
• If there is a choice between two different load cells because of overlapping ranges:
•
select a higher capacity load cell when you require minimum deflection of the
load cell
•
select a lower capacity load cell when you require maximum long term balance
or stability
If you don’t know the tensile strength of the material, refer to a Properties of Materials
handbook to obtain an approximate strength. To calculate the tensile strength in force
units for a specimen, use the following equation:
tensile strength x cross-sectional area
For example, for a standard ASTM tensile specimen (0.502 in wide, 0.125 in thick)
made with a material of tensile strength 5200 psi (from Materials Handbook) perform
the following calculation:
5200 x 0.502 x 0.125 = 328 lbf
This produces a recommendation of the 5 kN (1000 lb, 500kg) capacity load cell.
If you cannot determine an approximate value of tensile strength, use the highest
capacity load cell rated for the frame. Perform a preliminary test at a very slow speed to
obtain the load range required. You can then determine if a lower capacity load cell can
provide improved resolution.
Table 8 on page 74 lists the load cells that are recommended for use with these
frames.
If you have a load cell that is not listed, contact Instron® for advice on compatibility and
adapters that may be available for your load cell.

Adapters
Adapters let you connect grips or fixtures to the frame when the interfaces have
different connection sizes. There are two types of adapters: base adapters and coupling
adapters.
Product Support: www.instron.com
Base adapters
Base adapters let you connect grips and fixtures to the base of the load frame. The load
frame is supplied with a Type D base adapter installed. If you need to remove and re-
install the base adapter, for example to change the orientation, use the following
procedures.
Remove the base adapter
1.
Remove the compression spring located inside the adapter.
2.
Insert a 14 mm hex key into the base adapter, ensuring that it fits into the screw at
the base of the adapter.
3.
Loosen and remove the screw inside the adapter.
4.
Lift the adapter away from the base beam.

•
for 34TM-50 frame, torque to 200 N-m (147.5 ft-lb)
4.
Remove the hex key and insert the compression spring.
Coupling adapters
Coupling adapters let you attach grips and fixtures of different sizes to the load cell and
base adapter, providing more options for testing. There are two primary types:
• For tension testing only:
Tension coupling adapters, also known as self-aligning coupling adapters, which
provide a swivel connection and connect between clevis pin type interfaces. The
swivel action allows the grip or fixture to self-align in the direction of the test load,
thus minimizing any bending load on the specimen.
• For tension or compression testing:
Rigid coupling adapters which also connect between clevis pin type interfaces but
use check nuts to provide fixed connections. This type can also have a threaded
interface. These couplings are not self-aligning and the load string alignment is
dependent on the accuracy of load cell alignment during installation.
When assembling the load string, you may need to use adapters if the load cell
interface, or base adapter interface, differs from your grip interface. A coupling adapter
creates a secure connection between these two different interfaces.
If your grip or fixture interface is the same size as your load cell interface, then you can
connect these directly and you do not need an adapter. If, however, you need the self-

aligning feature that the adapter offers, you should use the appropriate self-aligning
coupling adapter.
Coupling types are listed from the load cell towards the accessory or from the frame
base towards the accessory. For example, if you need to connect a load cell with a Type
D (female) connector to a grip with a Type O (male) connector you require a Type Dm to
Of adapter.
Select Grips and Fixtures
A set of grips are installed on the system during installation by a service engineer. If your
testing requires it, you may need to install a different set to obtain optimum test results.
The selection of grips depends on the material, geometry and strength of the test
specimen.
In compression testing, the diameter or area of the anvil is important, in addition to the
maximum loading capacity.
For tensile testing:
• Make sure the tensile strength of the specimen does not exceed the maximum
loading capacity of the grips.
• Minimize the risk of slippage by:
•
selecting jaw faces with a surface area large enough to cover the tab (for
dumbbell-shaped specimens) or as much surface area as possible for parallel-
sided specimens.
•
ensuring that the specimen is gripped by at least 75% of the available jaw face
length.
•
using serrated jaw faces
• Breaks at the jaw face may be caused by:
•
Screw action grips - you may be using too much force when tightening the grips.
Use a torque wrench or switch to pneumatic grips for a consistent force.
•
Pneumatic grips - the pressure may be too high. Drop the pressure, but not to
the point where you get slippage.
•
Serrated faces - the serrations are damaging the specimen. Change to faces
that have more serrations per inch (less bite) or cover with masking tape or
similar material to soften the bite and prevent damage to the specimen.
Select Grips and Fixtures
Product Support: www.instron.com
Insert Jaw Faces into Grips
Different grips use different mechanisms for attaching jaw faces. Refer to the
documentation supplied with the grips for more information.
Install grips
Before you begin, check the following:
• There is sufficient space between the load cell and the load frame base to install the
grips.
• The crosshead is stationary.
• The frame is in the disabled state, i.e. the white LED above the DISABLED indicator
on the frame control panel is illuminated.
• The crosshead limit stops on the load frame are set to prevent the upper and lower
grips from colliding with each other (refer to “Set the crosshead limit stops” on
page 104).
• The mating surfaces of the grips, load cell and the base adapter are free of dirt or
debris.
Refer to Figure 22 on page 88 when following this procedure.
1.
For the upper grip, insert the adapter on the grip into the female clevis socket (1 in
Figure 22) on the load cell adapter.
2.
Align the clevis holes (2 in Figure 22)and insert the clevis pin (3 in Figure 22)
through the holes.
3.
Secure the clevis pin in position with the clevis pin clip (4 in Figure 22).
4.
Repeat steps 1 through 3 to install the lower grip onto the load frame base adapter.
5.
When both grips are installed, follow the procedure to preload the load string (refer
to “Preload the load string” on page 88).
Chapter: Assemble the load string
88
M10-17318-EN
Figure 22. Typical grip installation
Preload the load string
This procedure eliminates backlash and deflections within the load string which can
degrade the integrity of test results, especially when testing at high loads. The
procedure involves preloading the entire load string and then hand-tightening all the
lock nuts on all the grips and couplings. Even when using self-aligning couplings on the
upper grip, it is good practice to preload the lower grip.
You will need a rigid specimen that is strong enough to sustain the preload value without
breaking. This means a specimen that can sustain a load that is:
• 10% above the expected test load, or
• the maximum load rating of the weakest component of the load string (grips or load
cell)
4

1
2
Preload the load string
Product Support: www.instron.com
whichever is less. For example, if your grips are rated at 1kN, the load cell at 2kN and
your expected test load is 500N then you should preload to at least 550N but not more
than 1kN.
Before inserting the specimen ensure that:
• The grips and couplings are installed but the lock nuts are not tightened.
• Crosshead travel limits are set (refer to “Set the crosshead limit stops” on
page 104).
• The value of load in the live display is near zero. If it is not, balance the load (refer to
“Balance a transducer configuration” on page 105).
• The load limits are set in the software to a value that matches the maximum load
capacity of the weakest component in the load string.
1.
Install the strong specimen.
2.
Increase the load on the load string to the chosen preload value.
Caution
Do not attempt to increase the load by jogging the crosshead. The collision

Materials testing systems are inherently hazardous. Read the chapter “Risk reduction
and safe use” on page 25 before using the testing system.
Testing a sample
The following two procedures are guidelines for steps that you would typically go through
when testing a group of specimens. Some steps include references to more detail in
separate sections.
These scenarios assume that a test method has already been created that satisfies your
testing requirements and provides required test parameters (e.g. specimen dimensions,
testing notes) on the test workspace.
The two scenarios describe testing with and without an interlock.
An interlock is an optional accessory that changes the behavior of the system
depending on whether the interlock circuit is open or closed. For example, the door on a
protective shield may include an interlock. When the interlock circuit is open (e.g. the
Chapter: Testing specimens
92
M10-17318-EN
shield door is open), the circuit is interrupted and the system is either disabled or
restricted as defined by the Operator Protection settings.
Testing with no interlock
This test scenario assumes the system has no accessories with an interlock and that the
start test method in Operator Protection settings is set to Frame control (the default).
Warnings
Set the load frame limit stops to limit crosshead travel, and set adequate transducer
limits to ensure the safe operation of the testing system.
Set all available limits before using the system to avoid crosshead overtravel, contact
between grips and fixtures, overloading any component of the load string, or overtravel
of a contacting extensometer.
Hazard - do not allow more than one person to operate a testing machine.
Operator injury may result if more than one person operates the testing machine. For
example, injury can occur if one person moves the crosshead or actuator while the other
is working inside the hazard area between the grips or fixtures.
Crush hazard - take care when installing or removing a specimen, assembly,
structure or load string component.
Installation or removal of a specimen, assembly, structure or load string component
involves working inside the hazard area between the grips or fixtures. When working in
this area, ensure that other personnel cannot operate any of the system controls. Keep
clear of the jaws of a grip or fixture at all times. Keep clear of the hazard area between
the grips or fixtures during actuator or crosshead movement. Ensure that all actuator or
crosshead movements necessary for installation or removal are slow and, where
possible, at a low force setting.
Flying Debris Hazard - Make sure that test specimens are installed correctly in grips
or fixtures in order to eliminate stresses that can cause breakage of grip jaws or
fixture components.
Incorrect installation of test specimens creates stresses in grip jaws or fixture
components that can result in breakage of these components. The high energies
involved can cause the broken parts to be projected forcefully some distance from the
test area. Install specimens in the center of the grip jaws in line with the load path.
Insert specimens into the jaws by at least the amount recommended in your grip
documentation. This amount can vary between 66% to 100% insertion depth; refer to
supplied instructions for your specific grips. Use any centering and alignment devices
provided.

Calibrate a transducer
Automatic calibration of a force or strain transducer
Warning
Do not adjust the current calibration point value for an automatic calibration without
first contacting Instron® Service. Adjusting the calibration point can negatively affect
the validity of the data from the transducer.
A strain transducer can be an LVDT transducer. If the system identifies the strain
transducer as an LVDT transducer, the Calibration point field becomes available for
automatic calibration. The calibration point field is intended primarily for Instron®
Service and should only be used by the service personnel. Contact Instron® Service for
assistance.
1.

in the console area to open System Details.
2.
In the System Settings area, select the icon for the transducer to open the Transducer
Settings dialog.
3.
Under Settings, select the transducer configuration in the Transducer configuration
field.
4.
Ensure that Calibration type is set to Automatic.
Automatic calibration uses the following basis for the calibration point value:
5.
Set the transducer to its zero point.
For force, zero point means no load on the system.
For strain, zero point means the starting point of the strain transducer (e.g. exten-
someter)

The calibration was successful if a value displays in the transducer live display area
and the transducer icon in System Details is no longer grayed.
9.
Close the Transducer Settings dialog.
10. Close System Details.
The calibration is saved with the transducer configuration and is restored whenever the
transducer configuration is selected.
The transducer is now calibrated and ready for testing. The transducer must be
associated with a measurement in a method. Verify that the method used for testing
includes a measurement that is linked to the transducer configuration for this
transducer.
Manual calibration
During a manual calibration, you apply a measured physical force to the transducer and
the system calibrates on the signal that is output as a result of that force. For force
calibration, you can hang a measured weight from the load cell. For strain calibration,
you can install the extensometer on a specially designed calibration jig to apply a
precise deflection to the extensometer.
The system only saves the values entered for a manual calibration after there is a
successful calibration. If you select a different transducer configuration or close the
dialog before calibrating a transducer configuration, the calibration fields revert to the
default values for that configuration.

is 100 kN and the calibration point is 50 kN.
The range for a valid calibration point value is between:
