GB/T 17394.2-2012 "Metallic materials—Leeb hardness test—Part 2: Verification and calibration of hardness testers" specifies the methods for verifying and calibrating Leeb hardness testers. It mainly includes direct verification (checking the functions of individual components such as the impact device and display unit) and indirect verification (verifying the overall accuracy using standard hardness blocks on specified materials). The standard defines the verification conditions, procedures, and allowable limits for the repeatability and error of the hardness tester's indications. It aims to ensure that the metrological performance of Leeb hardness testers meets requirements during use and after maintenance, thereby guaranteeing the reliability and consistency of test results.
