The work of pr
22、eparing 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 committee. International organizations, governmental and non-governmental, i
23、n 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 accordance with the rules given in the ISO/IEC Directives, Part 2. The main tas
24、k 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 requires approval by at least 75 % of the member bodies casting a vote. Attentio
25、n 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.

EN ISO 3834-2:20051Quality requirements for fusion welding of metallic materials Part 2: Comprehensive quality requirements 1 Scope This part of ISO 3834 define
30、s comprehensive quality requirements for fusion welding of metallic materials both in workshops and at field installation sites. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For
31、 undated references, the latest edition of the referenced document (including any amendments) applies.

32、or 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 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 3834-1 apply. 4 Us
33、e of this part of ISO 3834 For general information on the use of this part of ISO 3834, ISO 3834-1 shall be used. In order to fulfil the quality requirements given in this part of ISO 3834, the conformity to relevant documents given in ISO 3834-5 shall be verified. In certain situations, e.g. where
34、manufacturing is more suited to ISO 3834-3 or ISO 3834-4, or where particular operations, such as heat treatment, are not undertaken, the requirements detailed in this part of ISO 3834 may be selectively amended or deleted. Otherwise, the requirements contained within this part of ISO 3834 shall be
35、adopted in full. EN ISO 3834-2:20052 5 Review of requirements and technical review 5.1 General The manufacturer shall review the contractual requirements and any other requirements, together with any technical data provided by the purchaser or in-house data when the construction is designed by the m
36、anufacturer. The manufacturer shall establish that all information necessary to carry out the manufacturing operations is complete and available prior to the commencement of the work. The manufacturer shall affirm its capability to meet all requirements and shall ensure adequate planning of all qual
37、ity-related activities. The review of requirements is carried out by the manufacturer to verify that the work content is within its capability to perform, that sufficient resources are available to achieve delivery schedules and that documentation is clear and unambiguous. The manufacturer shall ens
38、ure that any variations between the contract and any previous quotation are identified and the purchaser notified of any programme, cost or engineering changes that may result. Items in 5.2 are typically considered at or before the time of the review of requirements review. Items in 5.3 usually form
39、 part of the technical review and are considered during the initial planning stage. When a contract does not exist, e.g. items made for stock, the manufacturer is required to take into consideration the requirements of 5.2 while carrying out the technical review (see 5.3). 5.2 Review of requirements
40、 Aspects to be considered shall include the following: a) the product standard to be used, together with any supplementary requirements; b) statutory and regulatory requirements; c) any additional requirement determined by the manufacturer; d) the capability of the manufacturer to meet the prescribe
41、d requirements. 5.3 Technical review Technical requirements to be considered shall include the following: a) parent material(s) specification and welded joint properties; b) quality and acceptance requirements for welds; c) location, accessibility and sequence of welds, including accessibility for i
42、nspection and for non-destructive testing; d) the specification of welding procedures, non-destructive testing procedures and heat-treatment procedures; e) the approach to be used for the qualification of welding procedures ; f) the qualification of personnel; g) selection, identification and/or tra
43、ceability (e.g. for materials, welds); h) quality-control arrangements, including any involvement of an independent inspection body; i) inspection and testing; EN ISO 3834-2:20053j) sub-contracting; k) post-weld heat treatment; l) other welding requirements, e.g. batch testing of consumables, ferrit
44、e content of weld metal, ageing, hydrogen content, permanent backing, use of peening, surface finish, weld profile; m) use of special methods (e.g. to achieve full penetration without backing when welded from one side only); n) dimensions and details of joint preparation and completed weld; o) welds
45、 which are to be made in the workshop, or elsewhere; p) environmental conditions relevant to the application of the process (e.g. very low-temperature ambient conditions or any necessity to provide protection against adverse weather conditions); q) handling of non-conformances. 6 Sub-contracting Whe
46、n a manufacturer intends to use sub-contracted services or activities (e.g. welding, inspection, non-destructive testing, heat treatment), information necessary to meet applicable requirements shall be supplied by the manufacturer to the sub-contractor. The sub-contractor shall provide such records
47、and documentation of his work as may be specified by the manufacturer. A sub-contractor shall work under the order and responsibility of the manufacturer and shall fully comply with the relevant requirements of this part of ISO 3834. The manufacturer shall ensure that the sub-contractor can comply w
48、ith the quality requirements as specified. The information to be provided by the manufacturer to the sub-contractor shall include all relevant data from the review of requirements (see 5.2) and the technical review (see 5.3). Additional requirements may be specified as necessary to assure sub-contra
49、ctor compliance with technical requirements. 7 Welding personnel 7.1 General The manufacturer shall have at his disposal sufficient and competent personnel for the planning, performing and supervising of the welding production according to specified requirements. 7.2 Welders and welding operators Welders and welding operators shall be qualified by an appropriate test. The ISO documents to which it is required to conform to fulfil the quality requirements are specified in ISO 3834-5:2005, Table 1, for arc welding, electron beam welding, laser
