The Erweka tester tests a tablet placed on the lower anvil and a weight moving along a rail transmits pressure slowly to the tablet. [5] The Dr.Schleuniger Pharmatron tester operates in a horizontal position. An electric motor drives an anvil to compress a tablet at a constant rate. The tablet is pushed against a stationary anvil until it ...

A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels .
The history of the Schleuniger Group as it is known today started in 1991 when Dr. Gerhard Jansen (Chairman BOD until 2009) and Martin Strehl (CEO until 2009) acquired Sutter Electronic AG located in Thun, Switzerland. At that time Sutter Electronic AG had 30 employees and generated a revenue of 5 million CHF with wire processing machines and ...
A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1]
Brinell hardness test (HB) BHN and HBW are widely used [7] Knoop hardness test (HK), for measurement over small areas, widely used to test glass or ceramic material. [8] Janka hardness test, for wood; Meyer hardness test; Rockwell hardness test (HR), principally used in the USA. HRA, HRB and HRC scales are most widely used.
Typical lectromechanical Universal Testing Machine Test fixture for three point flex test. A universal testing machine (UTM), also known as a universal tester, [1] universal tensile machine, materials testing machine, materials test frame, is used to test the tensile strength (pulling) and compressive strength (pushing), flexural strength, bending, shear, hardness, and torsion testing ...
It was neither the first hardness tester nor the first to be called a durometer (ISV duro-and -meter; attested since the 19th century), but today that name usually refers to Shore hardness; other devices use other measures, which return corresponding results, such as for Rockwell hardness.
