标准简介
Sets out requirements for the measurement of the Rockwell superficial hardness of metals when using the N and T scales, and for the installation, calibration and maintenance of the testing machine. It also specifies requirements for the calibration of standard hardness blocks and diamond cone and steel ball indenters. In this edition the testing and calibration requirements have been combined into one Standard.
