impact body’s rebound velocity over its impact velocity, multiplied by 1000. Harder materials produce a higher rebound velocity than softer materials. For a specific group of material (e.g. steel, aluminum. etc.), Leeb hardness value represents a direct relationship to its hardness properties. For ordinary metal, conversion curves of hardness HL versus other standard static hardness (HB, HV, HRC, etc.) are available, enabling you to convert HL into other hardness values. 1.2.

2.1. Introduction HARTIP 2000 is an innovative portable Leeb hardness tester with our new patent technology which makes HARTIP 2000 a universal impact direction hardness tester. It is no need to set up impact direction when taking measurement by any angle. Therefore, HARTIP 2000 offers a linear accuracy comparing to the angle compensating method. HARTIP 2000 is also a cost saving hardness tester and has many other features. 2.2. Specifications Principle Leeb hardness measurement Accuracy ±0.3% @ HL=800 Repeatability ±2HL Display Digital LCD with backlight Impact direction Universal angle type Hardness scale HL/HRC/HRB/H ...

The coupling surface between the sample and base plate should be flat, plane parallel and ground. A thin proper layer of coupling paste is to be applied to the contact surface of the sample. The sample should be firmly pressed against the surface of the base plate by moving it with a circular motion. The direction of impact should be perpendicular to the coupling surface. For the coupling operation, the following prerequisites must be fulfilled: The contact surface of the sample and the surface of the base plate must be flat, plane parallel and ground. The direction of the test impact must be perpendicular to the coupled surfac ...

For test sample of curving surface with radius of curvature R less than 30mm, a small support ring should be used.
