The PATTERSON® Autoclave-Style Grease Kettle can be used for the complete grease manufacturing cycle - saponification, grease finishing and cooling.
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). It measures the coefficient of restitution. It is a form of . See moreThe Equotip (later on also called simultaneously as Leeb method) rebound hardness test method was developed in the year 1975 by Leeb and Brandestini at Proceq SA to .

See moreDepending on the probe (“impact device”) and indenter (“impact body”) types that vary by geometry, size, weight, material and spring force, . See more• Meyer hardness test See more Using an ultrasonic hardness tester, the Leeb Rebound tester can inspect the parts below 2mm (0.11″) supported or combined with a heavier .
Another well-known principle for portable hardness testers is the rebound method. The DynaMIC and DynaPOCKET (Krautkramer), for example, measure the velocity of a propelled impact . The core principle of the Leeb method revolves around measuring energy loss. During the test, an impact body strikes the metallic surface. The resulting loss of energy due to material deformation is meticulously measured, . The Leeb hardness test is of the dynamic or rebound type, which primarily depends both on the plastic and on the elastic properties of the material being tested. The .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 .
The Leeb hardness test (LHT with test value of L D ) is a rebound hardness test, originally developed for metals, that has been correlated with the Unconfined Compressive . The Leeb hardness number (L) is calculated from the ratio of the rebound velocity to the impact velocity of a spherically shaped tungsten carbide, silicon nitride, or diamond .
