8、ies). 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 and
9、 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,
10、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 cast
11、ing 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 15614-5 was prepared by the European Committee for Standardization (CEN) in collabora
12、tion with Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification requirements in the field of metal welding, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

23、IN, in collaboration with Technical Committee ISO/TC 44 “Welding and allied processes”. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2004, and conflicting national standards shall be
24、withdrawn at the latest by September 2004. Annex A is informative. Annex ZA is normative. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). According to the CEN/CENE
25、LEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malt

However, this sta
27、ndard does not invalidate previous welding procedure tests made to former national standards 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 which should be made in acco
28、rdance with this standard.

This standard specifies how a preliminary welding procedure specification is qualified by welding pr
29、ocedure tests. This standard defines the conditions for the execution of welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the range of variables listed in clause 8. Tests shall be carried out in accordance with this standard. A
30、dditional tests may be required by application standards. This standard applies to the arc welding of titanium, zirconium and their alloys in all product forms. Arc welding is covered by the following processes in accordance with EN ISO 4063. 131 - metal inert gas welding, MIG welding 141 - tungsten
31、 inert gas welding, TIG welding 15 plasma arc welding The principles of this standard may be applied to other fusion welding processes. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

40、lding procedure test The welding and testing of test pieces shall be in accordance with clauses 6 and 7. The welder or welding operator who undertakes the welding procedure test satisfactorily in accordance with this standard is qualified for the appropriate range of qualification according to EN IS
41、O 9606-5 or EN 1418 providing that the relevant testing requirements are met. 6 Test piece 6.1 General The welded joint to which the welding procedure will relate in production shall be represented by making a standardized test piece or pieces, as specified in 6.2. Where the production/joint geometr
42、y requirements do not represent the standardized test pieces as shown in this standard, the use of EN ISO 15613 shall be required. 6.2 Shape and dimensions of test pieces 6.2.1 General The length or number of test pieces shall be sufficient to allow all required tests to be carried out. Additional t
43、est pieces, or longer test pieces than the minimum size, may be prepared in order to allow for extra and/or for re-testing specimens (see 7.7). For all test pieces except branch connections (see Figure 4) and fillet welds (see Figure 8) the material thickness, t, shall be the same for both plates/pi
44、pes to be welded. The thickness and/or outside pipe diameter of the test pieces shall be selected in accordance with 8.3.2.1 to 8.3.2.4. The shape and minimum dimensions of the test piece shall be as follows : 6.2.2 Butt joint in plate with full penetration The test piece shall be prepared in accord
45、ance with Figure 1. ISO 15614-5:2004(E) ISO 2004 All rights reserved 3 6.2.3 Butt joint in pipe with full penetration The test piece shall be prepared in accordance with Figure 2. NOTEThe word “pipe”, alone or in combination, is used to mean “pipe”, “tube” or “hollow section”. 6.2.4 T-joint The test
46、 piece shall be prepared in accordance with Figure 3. This may be used for fully penetrated butt welds or fillet welds. 6.2.5 Branch connection The test piece shall be in accordance with Figure 4. The angle is the minimum to be used in production. This may be used for fully penetrated joints (set-on
47、 or set-in or set-through joint) and for fillet welds. 6.3 Welding of test pieces Preparation and welding of test pieces shall be carried out in accordance with the pWPS, and under the general conditions of welding in production which they shall represent. Welding positions and limitations for the a
48、ngle of slope and rotation of the test piece shall be in accordance with EN ISO 6947. If tack welds are to be fused into the final joint they shall be included in the test piece. Welding and testing of the test pieces shall be witnessed by an examiner or examining body. ISO 15614-5:2004(E) 4 ISO 200
