IS 3600 : Part 9 : 2025/ISO 17639 : 2022 Welded Joints and Weld Metal - Method of Test - Part 9 Destructive Tests on Welds in Metallic Materials - Macroscopic and Microscopic Examination of Welds
NATIONAL FOREWORD
This Indian Standard (Part 9) (Fourth Revision) which is identical to ISO 17639 : 2022 'Destructive tests on welds in metallic materials - Macroscopic and microscopic examination of welds' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Welding General and its Applications Sectional Committee and approval of the Metallurgical Engineering Division Council.
This standard was first published in 1966 and subsequently revised in 1973, 1985 and 2022. This first revision of the standard was published in to cover various tests on fusion welded joints and weld metals in steel. The second revision of this standard was published in to bring the test and test requirements in line with the other International Standards published so far by revising the standard in 9 Parts. The third revision of this standard was published in to align it with the ISO 17639 : 2003. This revision has been brought out to align it with latest version of ISO 17639 : 2022, to harmonize it with the latest developments that have taken place at International level.
In this revision, following major changes have been incorporated:
a) Clause 2 has been updated; and
b) The designations according to ISO/TR 15608 have been updated in 10.
This Indian Standard is published in various parts. Other parts in this series are:
Part 1 Destructive tests on welds in metallic materials - Tensile test on cruciform and lapped joints
Part 2 Destructive tests on welds in metallic materials - Impact tests - Test specimen location, Notch orientation and examination
Part 3 Destructive tests on welds in metallic materials - Transverse tensile test
Part 4 Destructive tests on welds in metallic materials - Longitudinal tensile test on weld metal in fusion welded joints
Part 5 Destructive tests on welds in metallic materials - Bend tests
Part 8 Destructive tests on welds in metallic materials - Fracture test
The text of ISO standard has been approved as suitable for publication as an 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.
