GB/T 17394.3-2022 specifies the calibration specifications for standard Hardness blocks in the Richter Hardness test of metal materials. The standard clearly calibrates Environmental requirements, explains the operation process in detail, and strictly controls the accuracy of the equipment used for calibration. Through standard operation, the Richter Hardness value of the standard Hardness block is accurately determined to ensure that its Hardness value is accurate and traceable. Accurately calibrated Hardness blocks are the benchmark for calibrated Leeb hardness testers, providing a reliable basis for the Richter hardness testing of metal materials, and strongly supporting the mass testing and performance evaluation of products in the metal industry.
