    Abstract - (Show below) - (Hide below)

    Specifies requirements for the measurement of the Rockwell hardness of metals 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 the one Standard.

    Scope - (Show below) - (Hide below)

    This Standard sets out methods for measuring the Rockwell hardness of metals and metal products using scales A, B, C, D, E, F, G, H and K. It includes requirements for the installation and calibration of the testing machine, and recommendations for its maintenance by the user.This Standard does not cover the special requirements of the Rockwell superficial hardness test as these are dealt with in AS 2025, nor does it cover the testing of materials other than metals. This Standard does not preclude the use of portable hardness testing machines which meet the appropriate requirements of Section 2.
