Measure the compressibility of compound
materials
A hardness testing machine engineered to measure the compressibility of compound materials has been introduced by Indentec.
A hardness testing machine engineered to measure the compressibility of compound materials has been introduced by Indentec Based on one of the Stourbridge Company's Microprocessor controlled Rockwell testers, the unit is operated by software designed for the repetitive testing of compressible semi hard components such as brake pads and clutch linings

Computer packages automate hardness testers
Two new computer packages enable digital hardness testing machines to be upgraded to fully automatic operation and can be retrofitted to Vickers Micro hardness or Brinell full load testers.
Using a mix of standard and special Rockwell scales, the test provides a quantitative indication of compressibility, employing ball indenters upto 1 inch diameter with a preload of 10 kgf and total loads upto 30 kgf.
Both preload and total loads are applied for extended dwell times as required by relevant standards under the control of the software.
The depth of the resulting indentation provides the compressibility measure, which the software converts to the user's own scale of classification.
The compressibility, which is said to be reliable indicator of the frictional properties of the material, is statistically analysed and printed out.
