Approved standardising systems for Rockwell, Vickers, and Brinell scales is a response to growing concern in industry about the maintenance of hardness standards
Indentec has launched a series of accredited standardising machines for institutions and manufacturers keen to ensure that the hardnesses are always measured precisely to official standards.
The 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.
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% of the test force, as required by the relevant standard.
The machines are based on standardising models in Indentec's own standardising laboratory, which is accredited by Ukas for the three scales.
All touchscreen controlled benchtop units, they are driven by customised software and use proven deadweight technology, rather than load cells, to ensure calibration stability over the long term, with no drift.
As the blocks are calibrated, the hardness data is processed automatically by the software to produce the usually detailed statistics needed for traceability.
A dedicated range of optional accessories can be supplied to enable the machines to perform the varied testing functions that characterise standardising work.
