15、dorsement notice The text of ISO 17654:2011 has been approved by CEN as a EN ISO 17654:2011 without any modification. BS EN ISO 17654:2011ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing
16、 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 non-governmental, in liais
17、on 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, Part 2.The main task of tech
18、nical 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 casting a vote.Attention is drawn
19、 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 17654 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 6, Resistance wel

22、copeThis International Standard specifies the pressure test method to be applied to resistance-seam-welded specimens of different types of materials with single sheet thicknesses ranging from 0,3 mm to 3,2 mm.The purpose of this pressure test is to determine the suitability of the material, welding
23、equipment, welding parameters and of other factors on a tank, a vessel or a container for liquids or gases, which are manufactured by resistance seam welding.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only th

26、l apply to the preparation of all specimens. Materials, thickness, heat treatment and condition of the sheets used for the test specimens shall be identical to those used for welding the actual component. For a given welding process, the welding equipment used to produce the test specimens shall hav
27、e a specification comparable to that used for welding the actual component.In special cases, e.g. transfer of welding parameters into production lines, the same parameters should be used. It has to be ensured that the electrodes that are used to weld the specimens shall be of the same material and g
28、eometry as the ones used for welding the actual component.5.2 DimensionsDimensions of resistance-seam-welded test specimens, of type A and type B, are given in Figure 1.

No leaks (in the form of bubbles escaping from any of the seam welds after a specified time) are permitted.I

34、s, the test shall be conducted in air using internal water pressure. No leakage of water from any of the seam welds is permitted during the specified time.The time during which the test pressure is to be maintained shall be specified. This generally depends on the material, the weld process and the
35、product specification.7 Test reportThe test report shall include at least the following information:a) a reference to this International Standard (ISO 17654:2011);b) the test materials and sheet thicknesses;c) chemical composition and mechanical properties of the test materials;d) the geometry of th
