19、eration of national standards bodies (ISO member bodies). 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 comm

20、ittee. International organizations, governmental and 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 accorda

21、nce with the rules given in the ISO/IEC Directives, 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

22、 approval by at least 75 % of the member bodies casting 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 15614-3 was prepared by the Europ

23、ean Committee for Standardization (CEN) Technical Committee CEN/TC 121, Welding, in collaboration with Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the field of metal welding, in accordance with the Agreement on technical cooperation

24、 between ISO and CEN (Vienna Agreement). Requests for official interpretations of any aspect of this part of ISO 15614 should be directed to the Secretariat of ISO/TC 44/SC 10 via your national standards body. A complete listing of these bodies can be found at www.iso.org. ISO 15614 consists of the

25、following parts, under the general title Specification and qualification of welding procedures for metallic materials Welding procedure test: Part 1: Arc and gas welding of steels and arc welding of nickel and nickel alloys Part 2: Arc welding of aluminium and its alloys Part 3: Fusion welding of no

29、alification of welding procedures for metallic materials Welding procedure test Part 3: Fusion welding of non-alloyed and low-alloyed cast irons 1 Scope This part of ISO 15614 specifies how a preliminary welding procedure specification (pWPS) for production and repair welding of non-alloyed and low-

30、alloyed cast irons is qualified by fusion welding procedure tests. This part of ISO 15614 defines the conditions for execution of the welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the range of a defined list of variables. Th

31、is part of ISO 15614 is applicable to all new welding procedures. However, it 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

32、 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. This part of ISO 15614 is applicable to welding non-alloyed and low-alloyed grey cast iron castings according to: EN 1561; EN 1562; EN 1563; and EN 1

33、564. The principles of this part of ISO 15614 are also applicable for welding cast iron to steel or to other unalloyed and low-alloyed cast iron materials. 2 Normative references The following referenced documents are indispensable for the application of this document.
