The work of preparing International Standards is normally carried out through ISO
4、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, also take part in the work. ISO collaborates clo

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the Technical Committees are circulated
6、 to member bodies for voting. Publication as an International Standard requires approval by at least 75 % of member bodies casting a vote.

17、 -,-,- -,-,- ISOISO 9606-3:1999(E) 1 Introduction This standard covers the principles to be observed in the approval testing of welder performance for the fusion welding of copper and copper alloys. The term copper stands for copper and weldable copper alloys. The ability of the welder to follow ver
18、bal or written instructions and testing of his skill are important factors in ensuring the quality of the welded product. Testing of skill to this standard depends on welding methods in which uniform rules and test conditions are complied with, and standard test pieces are used. The test weld can be
19、 used to approve a welding procedure and a welder provided that all the relevant requirements, e.g. test piece dimensions, are satisfied (see relevant part of EN 288-2). 1 Scope This standard specifies essential requirements, ranges of approval, test conditions, acceptance requirements and certifica
20、tion for the approval testing of welder performance for the welding of copper. This standard applies to the approval testing of welders for the fusion welding of copper. This standard is intended to provide the basis for the mutual recognition by examining bodies for approval relating to welders com
21、petence in the various fields of application. Tests will be carried out in accordance with this standard unless more severe tests are specified by the relevant application standard when these are applied. During the approval test the welder should be required to show adequate practical experience an
22、d job knowledge (test non mandatory) of the welding processes, materials and safety requirements for which he is to be approved; information on these aspects is given in Annex A. This standard is applicable when the welders approval testing is required by the purchaser, by inspection authorities or
23、by other organizations. The welding processes referred to in this standard include those fusion welding processes which are designated as manual or partly mechanized welding. It does not cover fully mechanized and automatic processes (see 5.2). This standard covers approval testing of welders for wo
24、rk on semi-finished and finished products made from wrought, forged or cast material types listed in 5.4. The certificate of approval testing is issued under the sole responsibility of the examiner or examining body. 2 Normative references This European Standard incorporates by dated or undated refe
