BS EN ISO 5178-2011 pdf download.Destructive tests on welds in metallic materials – Longitudinal tensile test on weld metal in fusion welded joints (ISO 5178:2001). This International Standard specifies the sizes of test specimens and the test procedure for carrying out longitudinal tensile tests on cylindrical test specimens in order to determine the mechanical properties of weld metal in a fusion welded joint. This International Standard applies to metallic materials in all forms of product with joints made by any fusion welding process, having joint sizes that are sufficient to obtain cylindrical test specimens with dimensions in accordance with ISO 6892. Unless specified otherwise for specific points in this International Standard, the general principles of ISO 6892 apply. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, this publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 6892, Metallic materials — Tensile testing at ambient temperature. 3 Principle An increasing tensile load is continuously applied until rupture occurs in a cylindrical test specimen taken longitudinally from the weld metal in a welded joint. Unless otherwise specified, the test shall be carried out at ambient temperature (23 ± 5) °C. 4 Symbols and abbreviated terms The symbols and abbreviated terms to be used for the longitudinal tensile tests are specified in ISO 6892. 5 Removal of test specimens 5.1 Location The test specimen shall be taken longitudinally from the welded joint of the manufactured product or from the test piece. After machining, the parallel length of the test specimen shall consist only of weld metal (see Figures 1 and 2). To enable correct positioning of the test specimen in the joint, the joint cross-section at both ends of the test specimen can be macroetched. 5.2 Marking Each test piece shall be marked in order to identify its exact location in the manufactured product or in the joint from which it has been removed. Each test specimen shall be maried in order to identify its exact location in the test piece from which...
