Scope

This verification system table is suitable for verifying Vickers hardness meters with a test force of 49.03 to 980.7 N and a measurement range of 5 to 1,000 HV. It specifies the use of the national reference standard for Vickers hardness units (HV (kgf/mm2)) and the metrological parameters of the reference standard, as well as the procedure for transferring Vickers hardness unit values from the working reference and standards to the working measuring instruments. It also specifies the corresponding uncertainty and basic verification methods.
