GB/T 230.2-2022 inspection and calibrate of hardness gauge and indenter in rockwell hardness test of focused metal materials. The standard specifies the inspection calibrate items, covering the force value accuracy of hardness gauge, indication Repeatability, as well as the geometric size and surface roughness of indenter. Strict requirements are put forward for the accuracy of standard blocks, measuring tools and other equipment used in inspection calibrate, and the operation process is described in detail. Through the implementation of specifications, the performance of Rockwell hardness tester and indenter is guaranteed to be reliable, which lays a solid foundation for the accurate testing of rockwell hardness of metal materials and helps the mass inspection and performance evaluation of metal materials.
