GB/T 17394.2-2022 "Metallic materials — Leeb hardness test — Part 2: Verification and calibration of hardness testers" specifies the direct and indirect verification methods for Leeb hardness testers. Direct verification includes the inspection of the dimensions and performance of the impact body, ball tip, and support ring. Indirect verification assesses the overall performance of the equipment using standardized hardness blocks. The standard also outlines the requirements for the verification environment temperature and traceability of measurements. It applies to hardness testers with different types of impact devices, providing a basis for controlling equipment performance and ensuring the reliability of test results.
