The work of preparing Internatio
22、nal 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, in liaison with ISO
23、, 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 task of technical com
24、mittees 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. Attention is drawn to the
25、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 3834-3 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requ
26、irements in the field of metal welding. This second edition cancels and replaces the first edition (ISO 3834-3:1994), which has been technically revised. ISO 3834 consists of the following parts, under the general title Quality requirements for fusion welding of metallic materials: Part 1: Criteria
27、for the selection of the appropriate level of quality requirements 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 3

Requests for official interpretations of any aspect of this part of ISO 3834 should be directed to the Sec
29、retariat of ISO/TC 44/SC 10 via your national standards body, a complete listing which can be found at http:/www.iso.org. EN ISO 3834-3:20051Quality requirements for fusion welding of metallic materials Part 3: Standard quality requirements 1 Scope This part of ISO 3834 defines standard quality requ
30、irements 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 undated references, the lat

33、or 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 manufacturing is more suited
34、 to 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 adopted in full. EN ISO 3834-3:20052 5 Rev
35、iew 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 manufacturer. The manufacturer shall establ
36、ish 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 quality-related activities. The review of requ
37、irements 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 ensure that any variations between the contra
38、ct 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. Items in 5.3 usually form part of the technical review and are considered
39、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 Aspects to be considered shall include the follo
40、wing: 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 prescribed requirements. 5.3 Technical review Technical re
41、quirements 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 inspection and for non-destructive testing; d) the
42、 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 traceability (e.g. for materials, welds); h) quality-
43、control arrangements, including any involvement of an independent inspection body; i) inspection and testing; EN ISO 3834-3:20053j) sub-contracting; k) post-weld heat treatment; l) other welding requirements, e.g. ferrite content of weld metal, ageing, hydrogen content, permanent backing, use of pee
44、ning, 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 which are to be made in the workshop, or elsewhere; p) environmental conditions
45、 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 When a manufacturer intends to use sub-contracted services or activities (e.g. weld
46、ing, 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 and documentation of his work as may be specified by the manufacturer. A sub-con
47、tractor 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 with the quality requirements as specified. The information to be provided by the
48、 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-contractor compliance with technical requirements. 7 Welding personnel 7.1 General The
49、 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 beam welding and gas welding, and in ISO 3834-5:2005, Table 10, for other fusion w
