GB/T 230.3-2012 stipulates the calibration method of the standard Hardness block in the rockwell hardness test of metal materials. The standard applies to the standard Hardness block with 11 scales from A to T. The calibration process is described in detail, including the requirements for the calibration environment and equipment accuracy. Through standard operation, the Hardness block is accurately measured and assigned to ensure the accuracy and traceability of its Hardness value. Accurately calibrated Hardness blocks are the key to calibrating Rockwell hardness testers, providing reliable benchmarks for rockwell hardness testing of metal materials, effectively guaranteeing the conformity and credibility of test results, and widely serving the mass inspection link of the metal industry.
