The functionality, accuracy, and conformance to standards of the hardness testing apparatus and all measurement-related components must be guaranteed when pertinent measurements are conducted on components. There are specific guidelines for how this must be proved and tracked in the hardness testing standards (ISO, ASTM). Every test technique and loading level must comply with this monitoring criterion.

Calibration of a hardness tester is necessary to perform an initial accuracy check, for instance, on new equipment or after modifications.

Even after calibration, the hardness testing device’s accuracy needs to be periodically reviewed as part of a recurring daily or weekly test. For each test method and series of standards, the manner in which these tests are conducted and the permitted variances of the results are explicitly described (ASTM, ISO).

For the purpose of monitoring the hardness tester, all standard-compliant tests must be recorded.

NextGen’s BrinGen – 3000 Series – Digital Brinell and Automatic Brinell Hardness Tester test force accuracy is 62.5-250Kgf ≤ 1%; 500-3000Kgf ≤ 0.5%.
