Indentec checks brake pads
Keyword: Testing
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.
Using a mix of standard and special Rockwell scales, the test provides a quantitative indication of compressibility, employing ball indenters up to 1 inch diameter with a preload of 10 kgf and total loads up to 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 a reliable indicator of the frictional properties of the material, is statistically analysed and printed out.
