Calibration, verification, certification
The initial verification of hardness testers is carried out when the hardness testers are released from production. A "Verification Certificate" of the established form is issued for the hardness testers, which is included in the hardness tester delivery set.
Verification and calibration of portable hardness testers of the "MET" series is carried out according to the main hardness scales HRC, HB, HV, HSD.
Calibration according to additional (user) scales H1, H2, H3 (for example, according to the hardness scales HBW, HRB, HRN, HRT, etc.), as well as for metals that differ significantly in properties from steel (for example, aluminum and copper alloys, etc.) is carried out by the user according to the instructions provided in the hardness tester passport. The Rm scale of tensile strength is available, which is calculated from the HB scale according to GOST 22761 (Russian Federation).
The frequency of verification of hardness testers is once a year. Verification can be carried out by any metrological service of legal entities accredited for the right to verify hardness measuring instruments, regional Centers for Standardization and Metrology (CSM). The verification method together with the Passport are included in the hardness tester kit.
