GB/T 4340.2-2012 focus on the inspection and calibrate of Vickers hardness tester for metal materials. This standard specifies the inspection process of hardness gauge in initial use, periodicity and after maintenance, and clarifies the accuracy detection requirements for key parts such as hardness gauge loading system, indenter geometry, measurement device, etc. Through strict implementation of calibrate procedures, ensure that hardness gauge can accurately measure Vickers Hardness of metal materials, ensure that the test data of different time periods and different hardness gauges are unified and reliable, and build a solid foundation for the research and development, production and mass control of metal materials.
