15、-6:2007iv Foreword ISO (the International Organization for Standardization) is a worldwide federation 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

16、 which a technical committee has been established has the right to be represented on that committee. 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 a

17、ll matters of electrotechnical standardization. International Standards are drafted in accordance 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

18、 circulated to the member bodies for voting. Publication as an International Standard requires 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 In

19、ternational Standard (“state of the art”, for example), it may decide by a simple majority vote 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

20、valid or useful. Attention is drawn to the possibility that some of the elements of this document 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 proc

21、esses, Subcommittee SC 10, Unification of requirements in the field of metal welding. ISO/TR 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 requirement

22、s Part 2: Comprehensive quality requirements Part 3: Standard quality requirements Part 4: Elementary 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 implementin

23、g ISO 3834 Technical Report Requests for official interpretations of any aspect of this part of ISO 3834 should be directed to the Secretariat of ISO/TC 44/SC 10 via your national standards body, a complete listing of which can be found at http:/www.iso.org. CEN ISO/TR 3834-6:2007vIntroduction Weldi

24、ng 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 procedures be followed, or both. ISO 3834 deals with qual

25、ity 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 applied by manufacturers, in which case the meeting of its re

26、quirements 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 manufactured. However, its principles and many of its detai

27、led 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 to define requirements in the field of welding so that co

28、ntracting 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 done. This concept also applies to committees responsible

29、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 can serve as a basis for these purposes, as well as for the

30、demonstration of performance by those manufacturers implementing it. CEN ISO/TR 3834-6:2007blank1Quality requirements for fusion welding of metallic materials Part 6: Guidelines on implementing ISO 3834 1 Scope This part of ISO 3834 gives guidelines for the implementation of requirements given in th

31、e other parts of ISO 3834, and is intended to help manufacturers and users select that part of ISO 3834 appropriate to their needs. It is expected that they will already be familiar with ISO 3834 as a whole. 2 Normative references The following referenced documents are indispensable for the applicat

32、ion of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The following subclauses identify different ways w

37、hereby the manufacturer may select or be required to adopt ISO 3834. 4.2 Product standards Where product standards 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,

38、EN 12952, EN 13445 and EN 15085. 4.3 Purchasers and users Purchasers and users of welded products may specify 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

39、specific requirements for welding activities, ISO 3834-2, ISO 3834-3 and ISO 3834-4 should be used. 4.5 Quality 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

40、, ISO 3834-3 and ISO 3834-4 should be used. 4.6 Manufacturers Whenever manufacturers wish to give evidence 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 c

41、ommittees that draft product standards at the international, regional and national levels. ISO 3834-2, ISO 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 appropri

42、ate quality requirements for the products to be manufactured, taking account of the selection criteria given 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 compelli

43、ng reasons exist. In case of doubt, or where additional requirements are being considered, consultation with ISO/TC 44/SC 10 is recommended. CEN ISO/TR 3834-6:20073Where welding is involved in the manufacture of a product, the standards committee may define the documents to be applied or else take t

44、hem 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

45、standardization committee to select only those that would be acceptable. The development of tables linking parts of ISO 3834 (with or without other quality-related standards such as ISO 9001) to requirements other than those given in ISO 3834, is strongly discouraged. 6 Using other documents with IS

46、O 3834 Full conformity with ISO 3834-2, ISO 3834-3 and ISO 3834-4 may be achieved either by adopting the ISO documents according to ISO 3834-5, or applying other standards that provide equivalent technical conditions. Standards that do not provide equivalent conditions may be adopted if they are ref

47、erenced in product standards that are used in full by the manufacturer. Product standards that have been operated satisfactorily in service may be considered by a manufacturer as being recognized for application with ISO 3834. Where a manufacturer bases his demonstration of conformity to ISO 3834 on

48、 product standards, it is the responsibility of the manufacturer to apply the corresponding standards whether separately specified or incorporated in the product standard in their totality. It is the responsibility of the manufacturer to demonstrate technically equivalent conditions when standards o

49、ther than the ISO documents according to ISO 3834-5 are applied. Certificates issued following assessment by independent certification organizations or claims of compliance by a manufacturer with any part of ISO 3834 should clearly identify the documents used by the manufacturer and provide or reference evidence of technical equivalence as applicable. 7 Documentation and quality systems 7.1 Documentation In any control system there is a need for documentation. The term documentation embraces a range of different types of documents such
