The work of preparing International Standards is normally carried out through ISO technical
23、 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 closely with
24、 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 committees is to prepare International Standards. Draft Intern
25、ational 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 possibility that some of the elements of this document may
26、be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 5173 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 5, Testing and inspection of welds. This third edition cancels and replaces the seco
27、nd edition (ISO 5173:2000) which has been technically revised. Requests for official interpretations of any aspect of this International Standard should be directed to the Secretariat of ISO/TC 44/SC 5 via your national standards body, of which a complete listing can be found at www.iso.org.

29、s with cladding (subdivided into welds in clad plates and clad welds) and cladding without butt welds, in order to assess ductility and/or absence of imperfections on or near the surface of the test specimen. It also gives the dimensions of the test specimen. In addition, this International Standard
30、 specifies a method for making longitudinal root and face bend tests to be used instead of transverse bend tests for heterogeneous assemblies when base materials and/or filler metal have a significant difference in their physical and mechanical properties in relation to bending. This International S
31、tandard applies to metallic materials in all forms of product with welded joints made by any fusion arc welding process. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 transverse face bend test specimen for a butt weld TFBB specimen for whic

48、such a way that after machining the weld axis will remain in the centre of the test specimen or at a suitable position for testing. For longitudinal bend testing of butt welds, the test specimen shall be taken longitudinally from the welded joint of the manufactured product or from the welded test p
49、iece. The location and orientation of bend test specimens of cladding material shall be specified by the application standard or by agreement between the contracting parties. 5.3 Marking Each test piece shall be marked to identify its exact location in the manufactured product or in the joint from which it has been removed. If required by the relevant application standard, the direction of working (e.g. rolling or extrusion) shall be marked. Each test specimen shall be marked to identify its exact location in the test piece from which it
