Metallic materialsRockwell hardness test Method 2: Verification and calibration of testing machine (scales A, B, C, D, E, F, G, H, K, N, T PREFACE This Standard was prepared by the Standards Australia Committee MT-006, Mechanical Testing of Metals to supersede in part AS 1815.22002, Metallic materialsRockwell hardness test, Method 2: Verification and calibration of testing machines (scales A, B, C, D, E, F, G, H, K, N, T). This Standard is identical with, and has been reproduced from ISO 6508-2:2005, Metallic materialsRockwell hardness test, Method 2: Verification and calibration of testing machines (scales A, B, C, D, E, F, G, H, K, N, T). The objective of this Standard is to specify the method for verification and calibration of Rockwell hardness testing machines.

A normative annex is an integral part of a standard, where an informative annex is only for information and guidance. iiINTERNATIONAL STANDARD ISO 6508-2:2005(E) ? ISO 2005 All rights reserved 1Metallic materials Rockwell hardness test Part 2: Verification and calibration of testing machines (scales A, B, C, D, E, F, G, H, K, N, T) 1 Scope This part of ISO 6508 specifies a method of verification of testing machines for determining Rockwell hardness (scales A, B, C, D, E, F, G, H, K, N, T) in accordance with ISO 6508-1. It specifies a direct method for checking the main functions of the machine operation and an indirect method suitable for the overall checking of the machine. The indirect method may be used on its own for periodic routine checking of the machine in service. If a testing machine is also to be used for other methods of hardness testing, it shall be verified independently for each method. This part of ISO 6508 is applicable to portable hardness testing machines. 2 Normative references The following referenced documents are indispensable for the application of this document.
