The work of preparing International Standards is normall
8、y 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 non-governmental, in liaison with ISO, also take part in the
9、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, Part 2. The main task of technical committees is to prepare In
10、ternational 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 casting a vote. Attention is drawn to the possibility that some of

ISO 14329 was prepared in collaboration with the International Institute of Welding which has been approved by the ISO Council as an international stan

INTERNATIONAL STANDARD ISO 14329:2003(E) ISO 2003 All rights reserved 1 Resistance welding Destructive tests of welds Failure types and geometric measurements for resistance spot, seam and projection welds 1 Scope This International Standard specifies the defi
13、nitions of the geometric measurements and fracture types to be used in relation to the testing of resistance spot, projection and seam welds in which different loading configurations cause different stress distributions in the weld (see Figure 1). The aim of these definitions is to give a base for a

15、ns For the purposes of this document, the following terms and definitions apply. 2.1 Failure modes of specimens and components 2.1.1 interface failure fracture through the weld nugget between the sheets at the place of the interface See Figure 2. 2.1.2 partial plug failure fracture in which a combin
16、ation of plug and interface failures are present See Figure 3. 2.1.3 plug metal pulled from one sheet remaining attached to the surface of the other after testing See Figure 3. 2.1.4 plug failure fracture in the base metal, the heat affected zone (HAZ) or in the nugget leaving a lug See Figure 3. 2.
