With standardising machines, users can trace the calibration of all their in-house hardness testers directly to the official hardness reference source.

The first to develop standardising machines for the three most widely used scales, Indentec says that the systems are engineered to calibrate hardness test blocks to within plus/minus 0.1 per cent of the test force, as required by the relevant standard.

The Stourbridge hardness testing specialist says that the introduction of approved standardising systems for Rockwell, Vickers and Brinell scales is a response to growing concern in industry about the maintenance of hardness standards as quality demands become more stringent.
