NATIONAL FOREWORD

This Indian Standard (Part 5) (First Revision) which is identical to ISO 3834-5 : 2015 ‘Quality requirements for fusion welding of metallic materials — Part 5: Documents with which it is necessary to conform to claim conformity to the quality requirements of ISO 3834-2, ISO 3834-3 or ISO 3834-4 issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Welding General and its Applications Sectional Committee and approval of the Metallurgical Engineering Division Council.

This standard was originally published in 2003. The first revision of this standard has been undertaken to align it with the latest version of ISO 3834-5 : 2015.

This Indian Standard is published in five parts. The other parts in this series are:

Part 1 Criteria for the selection of the appropriate level of quality requirements

Part 2 Comprehensive quality requirements

Part 3 Standard quality requirements

Part 4 Elementary quality requirements

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 particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, it should be as read as ‘Indian Standard’.

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.
