The Leeb Rebound Hardness Test (LRHT) invented by Swiss company Proceq SA is one of the four most used methods for testing metal hardness. This portable method is mainly used for testing sufficiently large workpieces (mainly above 1 kg). [citation needed] It measures the coefficient of restitution. It is a form of nondestructive testing. History.The Leeb hardness testing, otherwise called as Leeb Rebound Hardness Test (LRHT), is considered as one of the four commonly used methods to test the hardness of the metal. It is a type of non-destructive testing used to inspect large sized workpieces weighing above 1 kg. Accuracy and Precision. Leeb hardness testing’s accuracy is contingent on the apparatus’s proper verification and calibration. The verification process entails utilizing standardized test blocks to check the instrument's precision.

Learn how the Leeb hardness tester provides quick and non-destructive material hardness assessments. Explore its working principles, benefits, and applications across various industries.When needing to perform hardness testing on-site or non-destructively – the Leeb hardness test provides portability and convenience. At Protolabs the majority of our datasheets include figures utilising the Brinell and Rockwell hardness tests, please see below for a selection metals we offer at Protolabs for CNC machining and their hardness values.The Leeb method principle uses a spherical tungsten carbide ball and a spring load to measure the hardness of a test piece. This method uses a rebound technique which measures the energy lost when the impact body hits the test sample. The accuracy of a Leeb test is dependent on correct setup and test conditions – surface roughness, test piece thickness, and mass are defined in the A956 standard. The A956 standard is not known to be specifically referenced by any current API standard however; the Equotip conveniently converts hardness measurement values and displays the .
Factors that affect the accuracy of a leeb, rebound type portable metal hardness tester.
Determination of the hardness of metallic materials according to Leeb is defined in the ISO 16859 and ASTM A956 standards. In this dynamic test method, the ratio of rebound velocity to impact velocity of a moving impactor is used to determine the hardness. The Leeb hardness test (LHT with test value of L D), introduced in 1975 by Dietmar Leeb (Leeb 1979), is a portable hardness tester, developed originally for measuring the strength of metallic materials, that has been adapted for prediction of σ c of rock (Kompatscher 2004).The Leeb Rebound Hardness Test (LRHT) invented by Swiss company Proceq SA is one of the four most used methods for testing metal hardness.
