EN ISO 17654:2011 (E) DIN EN ISO 17654:2011-12 3 1 ScopeThis International Standard specifies the pressure test method to be applied to resistance-seam-welded specimens of different types of materials with single sheet t

22、hicknesses ranging from 0,3 mm to 3,2 mm.The purpose of this pressure test is to determine the suitability of the material, welding 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 Normativ

Materials, thickness, heat treatment and condition of the sheets used for the test specimens shall be identical to those us

26、ed for welding the actual component. For a given welding process, the welding equipment used to produce the test specimens shall have 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 paramet

27、ers 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 geometry 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

30、ture as shown in Figure 2. The purpose of the restraining fixture is to restrict expansion of the specimen within the expansion range, G, indicated in Figure 2.The test specimen shall be connected to a supply of compressed air or water at the specified pressure and in the case of compressed air imme

31、rsed in a water bath. No leaks (in the form of bubbles escaping from any of the seam welds after a specified time) are permitted.EN ISO 17654:2011 (E) DIN EN ISO 17654:2011-12 5 (t2 t1)Key1 nuts to adjust G G expansion range (t1+ t2+ 20 mm) (restricted expansion)2 water or compressed air supply conn

33、15 MPa, whichever is the lower pressure.If a test pressure greater than 0,15 MPa is specified, for safety reasons, 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 pr

34、essure is to be maintained shall be specified. This generally depends on the material, the weld process and the 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

35、 sheet thicknesses;c) chemical composition and mechanical properties of the test materials;d) the geometry of the test specimens;e) welding method (seam welding);f) welding equipment and welding parameters;g) weld dimensions;h) test results, test pressure and time for which the pressure is maintained during the test, pressure fluid;i) any deviation(s) from this International Standard.EN ISO 17654:2011 (E) DIN EN ISO 17654:2011-12 6
