The work of preparing International Standards is normally carried out through

18、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 work. ISO collaborates

19、 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 International Standards. D

20、raft 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 the elements of this doc

21、ument may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 4136 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

23、men and the procedure for carrying out transverse tensile tests in order to determine the tensile strength and the location of fracture of a welded butt joint.This International Standard applies to metallic materials in all forms of product with joints made by any fusion welding process.Unless other

24、wise specified for specific points in this International Standard, the general principles of ISO 6892-1 and ISO 6892-2 apply.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For unda

25、ted references, the latest edition of the referenced document (including any amendments) applies.ISO 4063:2009, Welding and allied processes Nomenclature of processes and reference numbersISO 6892-1, Metallic materials Tensile testing at ambient temperature Part 1: Method of test at room temperature

26、ISO 6892-2, Metallic materials Tensile testing at ambient temperature Part 2: Method of test at elevated temperature3 PrincipleAn increasing tensile load is continuously applied until rupture occurs in a test specimen taken transversely from a welded joint.Unless otherwise specified, the test shall

27、be carried out at ambient temperature (23 5) C.4 Symbols and abbreviated termsThe symbols and abbreviated terms to be used for the transverse tensile tests are specified in Table 1 and represented in Figures 1 to 3.

29、mt Thickness of the welded joint mmtsThickness of the test specimen mmaThe term “pipe”, alone or in combination, is used to mean “pipe”, “tube” or “hollow section (without rectangular cross section)”.5 Preparation of test specimens5.1 LocationThe test specimen shall be taken transversely from the we

30、lded joint in such a way that, after machining, the weld axis remains in the middle of the parallel length of the test specimen. For small diameter pipes, the test may be carried out on whole pipe (see Figure 3). If not specified by the application standards or agreed upon between the contracting pa

31、rties, “small diameters” means D 8 mm. If thermal cutting or other cutting methods which could affect the cut surfaces are used to cut the test specimen from the welded plate or from the test piece, the cuts shall be made at a distance 8 mm from the surfaces of the final parallel length of the test

32、specimen. Thermal cutting shall not be used parallel to the original surface of the welded plate or of the test piece.5.4.3 Other metallic materialsShearing and thermal cutting are excluded, and only machining (e.g. sawing or milling) shall be used.5.5 Machining5.5.1 GeneralThe tolerances specified

33、in ISO 6892-1 and ISO 6892-2 shall apply.5.5.2 LocationIn general, the thickness of the test specimen, ts, shall be equal to the thickness of the parent metal near the welded joint see Figure 1 a). When a relevant application standard requires testing of the full thickness 30 mm, several test specim

34、ens may be taken to cover the full thickness of the joint see Figure 1 b). In such cases, the location of the test specimen in the welded joint thickness shall be identified.a) Full section testb) Multi specimen testNOTE The test pieces may overlap.Figure 1 Examples of the location of test specimens
