IS 1501 : Part 1 : 2025/ISO 6507-1 : 2023 Metallic Materials - Vickers Hardness Test - Part 1 Test Method
NATIONAL FOREWORD
This Indian Standard (Part 1) (Sixth Revision) which is identical to ISO 6507-1 : 2023 'Metallic materials - Vickers hardness test - Part 1: Test method' 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 1959 and subsequently revised in 1968, 1984, 2002, 2013 and 2020. This revision has been undertaken to align with the latest version ISO 6507-1 : 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 2 Verification and calibration of testing machines
Part 3 Calibration of reference blocks
Part 4 Tables of hardness values
The main changes compared to the previous edition are as follows:
a) Scope revised to include testing on metallic coatings and other inorganic coatings;
b) Added 7.6 - Metallic and other inorganic coatings;
c) Requirements have been added to the test report for reporting the surface curvature, if the curvature correction is applicable;
d) Added Annex H to cover coatings specific requirements;
e) Updated references.
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.
