NADCAP and Buehler
Buehler developed many methods to simplify material preparation and analysis for NADCAP accredited customers. The traceability
of hardness testing machines is a very important step for materials inspection. In order to ensure all testing is performed by a verified
machine, indirect verification needs to be performed on hardness reference blocks. Respective blocks are calibrated in accordance
with ISO and ASTM standards, as well as engraved with a grid on the top surface, which allows each verification test to meet indent
spacing requirement.
To ensure all verification measurements are performed as required (e.g. at a specific time, after scale change, after indenter change
etc.) , Buehler developed a special software module within the DiaMet hardness software. The verification program will prompt
operators to perform indirect verification tests as required. This way, full traceability is guaranteed and is clearly exhibited during
audits. For additional information contact your sales representative.
