IS 1586 : Part 2 : 2025/ISO 6508-2 : 2023 Metallic Materials - Rockwell Hardness Test - Part 2 Verification and Calibration of Testing Machines and Indenters
NATIONAL FOREWORD
This Indian Standard (Part 2) (Sixth Revision) which is identical to ISO 6508-2 : 2023 'Metallic materials - Rockwell hardness test - Part 2: Verification and calibration of testing machines and indenters' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Mechanical Testing of Metals Sectional Committee and approval of the Metallurgical Engineering Division Council.
This standard was first published in 1960 and subsequently revised in 1968, 1988, 2000, 2012 and 2018. This revision has been undertaken to align with the latest version ISO 6508-2 : 2023 to harmonize it with the latest developments that have taken place at international level.
This standard is published in three parts. Other parts in this series are:
Part 1 Test method
Part 3 Calibration of reference blocks
The text of ISO standard has been approved as suitable for publication as in Indian Standard without deviations. Certain terminologies and conventions are, however, not identical with those used in Indian Standard. Attention is especially drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, it should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards the current practice is to use a point (.) as the decimal marker.
