IS 18738 : Part 1 : 2024/ISO 15792-1 : 2020 Welding Consumables - Methods of Test - Part 1 Preparation of All-Weld Metal Test Pieces and Specimens in Steel, Nickel and Nickel Alloys
NATIONAL FOREWORD
This Indian Standard (Part 1) which is identical to ISO 15792-1 : 2020 'Welding consumables - Test methods - Part 1: Preparation of all-weld metal test pieces and specimens in steel, nickel and nickel alloys' 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.
The test pieces and specimens are used to determine the mechanical properties of all-weld metal, and this standard specifies the preparation of test pieces and specimens for all-weld metal tests in steel, nickel and nickel alloys.
The Committee decided to adopt ISO 15792-1 : 2020 standard under dual numbering system.
This Indian Standard is published in three parts. The other parts in this series are:
Part 2 Preparation of single-run and two-run technique test pieces and specimens in steel
Part 3 Classification testing of positional capacity and root penetration of welding consumables in a fillet weld
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 readas 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practiceis to use a point (.) as the decimal marker.
