Description

This Standard 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.

Scope

This Standard does not preclude the use of portable hardness testing machines which meet the appropriate requirements of Section 2.

This Standard does not meet the requirements of Rockwell scales A to K, as these are dealt with in AS 1815, nor does it cover the testing of materials other than metals.
