18、dies). 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 committee. International organizations, governmental an

19、d 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 accordance with the rules given in the ISO/IEC Directives,

20、 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 requires approval by at least 75 % of the member bodies cas

21、ting a vote. 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 15614-6 was prepared by the European Committee for Standardization (CEN) Technical C

29、part of ISO 15614 specifies how a preliminary welding procedure specification is qualified by welding procedure tests. It applies to the arc and gas welding of copper and copper alloys in all product forms. This part of ISO 15614 defines the conditions for the execution of welding procedure tests an

30、d the range of qualification for welding procedures for all practical welding operations within the range of variables listed in Clause 9. This part of ISO 15614 is applicable to all new welding procedures. However, it does not invalidate previous welding procedure tests made to former national stan

31、dards or specifications. Where additional tests have to be carried out to make the qualification technically equivalent, it is only necessary to do the additional tests on a test piece made in accordance with this part of ISO 15614. Additional tests may be required by application standards. The prin

32、ciples of this part of ISO 15614 may be applied to other fusion welding processes. 2 Normative references The following referenced documents are indispensable for the application of this document.

45、nt the standardized test pieces as shown in this part of ISO 15614, ISO 15613 shall be used. 7.2 Shape and dimensions of test pieces 7.2.1 General The length or number of test pieces shall be sufficient to allow all required tests to be carried out. Additional test pieces, or test pieces longer than

46、 the minimum size, may be prepared in order to allow for extra testing and/or for re-testing specimens (see 8.6). For all test pieces except branch connections (see Figure 5) and fillet welds (see Figure 4), the material thickness, t, shall be the same for both plates/pipes to be welded. If required

47、 by the application standard, the direction of plate rolling shall be marked on the test piece. The thickness and/or outside pipe diameter of the test pieces shall be selected in accordance with 9.3.2.1 to 9.3.2.4. The shape and minimum dimensions of the test piece shall be as given in 7.2.2 to 7.2.
