In this adopted standard, some terminology and conventions are, however, not identical to those used in Indian Standards. Attention is especially drawn to the following: a) Wherever the words ‘International Standard’ appear referring to this standard, they should be 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. Inthis adopted standard, reference appears to certain International Standards for which Indian Standards also exist. The corresponding Indian Standards which are to be substituted in their place are listed below along with their degree~f equivalence for the editions indicated: International Standard Corresponding Indian Standard Degree of Equivalence ISO 3834-1:1994 IS 15326 ( Part 1 ) :2003 Quality requirements Technically equivalent for welding — Fusion welding of metallic materials : Part 1 Guidelines for selection and use ISO 3834-4:1994 IS 15326 ( Part 4 ) :2003 Quality requirements do for welding — Fusion welding of metallic materials :Part 4 Elementary quality requirements 1s0 9001:2000 1s/ 1 s0 9001 : 2000 Quality management do system s — Requirements ISO 9002:1994 1S/1S0 9002:1994 Quality systems — Model do for quality assurance in production, installation and servicing ISO 9606-1:1994 IS 7310 (Part 1 ) : 1974 Approval tests for Partially equivalent welders working to approved welding procedures: Part 1 Fusion welding of steel IS 7318 (Part 1 ) : 1974 Approval tests for do welders when welding procedure approval is not required :Part 1 Fusion welding of steel ISO 9606-2:1994 IS 7318 (Part 2) : 1974 Approval tests for do welders when welding procedure approval is not required : Part 2 TIG or MIG welding of aluminium and its alloys ISO 9712:1999 IS 13805:1993 General standard for qualification do and certification of non-destructive testing personnel ( Continued on third cover) Is 15326 (Part3) :2003 ISO 3834-3: 1994 Indian Standard QUALITY REQUIREMENTS FOR WELDING — FUSION WELDING OF METALLIC MATERIALS PART 3 STANDARDS QUALITY REQUIREMENTS 1 Scope framework for the control of welding in the following cases: Case1 This part of ISO 3834 has been prepared such that To provide specific requirements for fusion welding in — it is independent of the type of welded con- contracts which require the manufacturer to have a struction to be manufactured; quality system other than ISO 9001 or ISO 9002; — if defines quality requirements for welding both in Case2 workshops and on-site; To provide specific requirements for fusion welding — it provides guidance for describing a manufac- as guidance to a manufacturer developing a quality turer’s capability to produce welde d constructions system; to meet specified requirements; Case3 — it mav also be used as a basis for assessing the manufacturer with respect to his welding capa- To provide specific requirements for references in bility. application standards which uses fusion welding as part of its requirements or in a contract between rel- This part of ISO 3834 is appropriate when demon- evant parties.
