GB/T 17394.3-2012 "Metallic materials—Leeb hardness test—Part 3: Calibration of reference blocks" specifies the calibration method for reference blocks used for the calibration of Leeb hardness testers. It covers the requirements for the material, manufacture, uniformity, and stability of the reference blocks, and details the calibration procedures performed on them using standard impact devices. The standard aims to establish a benchmark for the transfer of Leeb hardness values, ensuring the accuracy and traceability of the calibrated values of the reference blocks, thereby providing a reliable basis for the indirect verification of Leeb hardness testers.
