NATIONAL FOREWORD

This Indian Standard ( Part 3 ) which is identical with ISO 3834-3:1994 ‘Quality requirements forwelding — Fusion welding of metallic materials — Part 3 Standards quality requirements’ issued by theInternational Organization for Standardization ( ISO ) was adopted by the Bureau of Indian Standardson the recommendations of the Welding Applications Sectional Committee and approval of the MetallurgicalEngineering Division Council.

In this adopted standard, some terminology and conventions are, however, not identical to those usedin Indian Standards. Attention is especially drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should beread as ‘Indian Standard’.

b) Comma ( , ) has been used as a decimal marker while in Indian Standards, the current practiceis to use a point ( . ) as the decimal marker.

In this adopted standard, reference appears to certain International Standards for which Indian Standardsalso exist. The corresponding Indian Standards which are to be substituted in their place are listedbelow along with their degree~f equivalence for the editions indicated:

QUALITY REQUIREMENTS FOR WELDING —FUSION WELDING OF METALLIC MATERIALS

PART 3 STANDARDS QUALITY REQUIREMENTS

1 Scope

This part of ISO 3834 has been prepared such that

—

—

—

—

it is independent of the type of welded con-struction to be manufactured;

if defines quality requirements for welding both inworkshops and on-site;

it provides guidance for describing a manufac-turer’s capability to produce welded constructionsto meet specified requirements;

it mav also be used as a basis for assessing themanufacturer with respect to his welding capa-bility.

This part of ISO 3834 is appropriate when demon-stration of a manufacturer’s capability to producewelded constructions and to fulfill specified qualityrequirements, are specified in one or more of the fol-lowing:

— a contract between involved parties;

— an application standard;

— a regulatory requirement.

The requirements contained within this part ofISO 3834 may be adopted in full or may be selectivelydeleted by the manufacturer if not applicable to theconstruction concerned. They provide a flexible

framework for the control of welding in the followingcases:

Case 1

To provide specific requirements for fusion welding incontracts which require the manufacturer to have aquality system other than ISO 9001 or ISO 9002;

Case 2

To provide specific requirements for fusion weldingas guidance to a manufacturer developing a qualitysystem;

Case 3

To provide specific requirements for references inapplication standards which uses fusion welding aspart of its requirements or in a contract between rel-evant parties. It may however be more appropriate forISO 3834-4 to be used in such cases.

2 Normative references

The following standards contain provisions which,through reference in this text, constitute provisionsof this part of ISO 3834. At the time of publication, theeditions indicated were valid. All standards are subjectto revision, and parties to agreements based on thispart of ISO 3834 are encouraged to investigate thepossibility of applying the most recent editions of thestandards indicated below. Members of IEC and ISOmaintain registers of currently valid InternationalStandards.
