18、deration of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that com

19、mittee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accord

20、ance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard require

21、s approval by at least 75 % of the member bodies casting a vote. In exceptional circumstances, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority vo

22、te of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature and does not have to be reviewed until the data it provides are considered to be no longer valid or useful. Attention is drawn to the possibility that some of the elements of this docu

23、ment may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TR 3834-6 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding. ISO/TR

24、3834 consists of the following parts, under the general title Quality requirements for fusion welding of metallic materials: 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: El

25、ementary quality requirements 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 Part 6: Guidelines on implementing ISO 3834 Technical Report Requests for official interpretations of any aspect of this part

27、6:2007(E) ISO 2007 All rights reserved vIntroduction Welding is a special process in that the final result may not be able to be verified by testing. The quality of the weld is manufactured into the product, not inspected. This means that welding normally requires continuous control or that specific

28、 procedures be followed, or both. ISO 3834 deals with quality requirements in welding and has been prepared in order to identify those controls and procedures. ISO 3834 is not a quality system standard intended to take the place of ISO 9001, but a useful, additional tool for use when ISO 9001 is app

29、lied by manufacturers, in which case the meeting of its requirements needs to be recorded in certificates or documentation. However, ISO 3834 can be used independently of ISO 9001. ISO 3834 is intended for the fusion welding of metallic materials, and its application is independent of the products m

30、anufactured. However, its principles and many of its detailed requirements are also relevant for other welding and welding-related processes. Among other International Standards covering resistance welding and thermal spraying are ISO 14554 and ISO 14922, respectively. One of the aims of ISO 3834 is

31、 to define requirements in the field of welding so that contracting parties or regulators do not have to do this themselves. A reference to a particular part of ISO 3834 should be sufficient to demonstrate the capabilities of the manufacturer to control welding activities for the type of work being

32、done. This concept also applies to committees responsible for drafting product standards. ISO 3834 does not in itself require external assessment or certification. However, assessments by customers and certification by independent bodies are growing trends in commercial relations and the standard ca

33、n serve as a basis for these purposes, as well as for the demonstration of performance by those manufacturers implementing it.

35、 implementation of requirements given in the other parts of ISO 3834, and is intended to help manufacturers and users select that part of ISO 3834 appropriate to their needs.

41、PS welding procedure specification 4 Using ISO 3834 4.1 General ISO 3834-1 provides criteria for the selection and use of ISO 3834 as a whole. The following subclauses identify different ways whereby the manufacturer may select or be required to adopt ISO 3834. 4.2 Product standards Where product st

42、andards require control of fusion welding, ISO 3834 should be used to organize those welding activities. Product standards where compliance with ISO 3834 is required include EN 1090, EN 12732, EN 12952, EN 13445 and EN 15085. 4.3 Purchasers and users Purchasers and users of welded products may speci

43、fy in contract documents that manufacturers demonstrate their competence by compliance with ISO 3834. 4.4 Quality management systems in accordance with ISO 9001 Since ISO 9001 does not include specific requirements for welding activities, ISO 3834-2, ISO 3834-3 and ISO 3834-4 should be used. 4.5 Qua

44、lity management systems other than ISO 9001 For welding activities in quality management systems other than ISO 9001 that do not include specific requirements for welding activities, ISO 3834-2, ISO 3834-3 and ISO 3834-4 should be used. 4.6 Manufacturers Whenever manufacturers wish to give evidence

45、of their competence in fusion welding activities, the appropriate part of ISO 3834 should be used. 5 Incorporating ISO 3834 in product standards An important group of users of ISO 3834 is the committees that draft product standards at the international, regional and national levels. ISO 3834-2, ISO

46、3834-3 and ISO 3834-4 provide a range of quality requirements for welding. Committees drafting product standards are encouraged to select a part, or parts, of ISO 3834 that provide the appropriate quality requirements for the products to be manufactured, taking account of the selection criteria give

47、n in ISO 3834-1:2005, Clause 5. Each part of ISO 3834 is designed to provide a complete set of quality requirements; additional requirements should not need to be specified unless very compelling reasons exist. In case of doubt, or where additional requirements are being considered, consultation wit

48、h ISO/TC 44/SC 10 is recommended.

49、e the documents to be applied or else take them from the ISO documents specified in ISO 3834-5. The committee should also select the appropriate quality requirement standard or standards to be applied. Where a series of levels exist in the ISO documents in ISO 3834-5, e.g. for welding procedure qualification, it would be satisfactory for the standardization committee to select only those that would be acceptable.
