The work of preparing International
19、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 liaison with ISO, al
20、so take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1.
21、In particular the different approval criteria needed for the different types of ISO documents should be noted.

25、013INTERNATIONAL STANDARD ISO 8496:2013(E)Metallic materials Tube Ring tensile test1 ScopeThis International Standard specifies a method for a ring tensile test of tubes to reveal surface and internal defects by subjecting the test piece to strain until fracture occurs. This test may also be used to
26、 assess the ductility of tubes.The ring tensile test is applicable to tubes having an outside diameter exceeding 150 mm and a wall thickness no greater than 40 mm. The inside diameter shall be greater than 100 mm.2 PrincipleSubjecting a ring cut from the end of a tube to strain in the circumferentia
27、l direction until fracture occurs.3 ApparatusUse two circular pins, of equal diameter with parallel axes, and movable in relation to each other while still remaining parallel.In principle, the diameter of the pins shall be the minimum permissible from strength considerations but, provided that the i
28、nside diameter of the tube allows, should be at least 3 times the wall thickness of the tube to be tested (see Figure 1).Dimensions in millimetresFigure 1 ISO 2013 All rights reserved 1Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproductio
29、n or networking permitted without license from IHS-,-,-BS EN ISO 8496:2013ISO 8496:2013(E)4 Test piece4.1 The test piece shall be a ring cut from the tube with the end faces perpendicular to the axis.4.2 The length of the test piece (width of the ring) shall be approximately 15 mm. If the thickness
30、exceeds 15 mm, the length of the test piece may be equal to the thickness.4.3 The ends of the test piece shall be free from burrs. The edges may be rounded by filing or chamfered by other methods.NOTE Non-rounded or non-chamfered edges are permissible, if the test result meets the test requirements.
31、5 Procedure5.1 In general, the test shall be carried out at ambient temperature within the limits of 10 C to 35 C. The test carried out under controlled conditions shall be made at a temperature of 23 C 5 C.5.2 Place the ring cut from the tube over the pins. Subject the ring to strain by moving the
32、pins away from each other at a specified rate until it fractures.In cases of dispute, the rate shall not exceed 5 mm/s.5.3 Interpretation of the ring tensile test shall be carried out in accordance with the requirements of the relevant product standard. When these requirements are not specified, the
33、 test piece shall be considered to have passed the test if the expected fracture behaviour was obtained and no other cracks are visible without the use of magnifying aids.6 Test reportA test report shall be provided when so specified in the relevant product standard. In this case, the test report sh
34、all include at least the following information:a) a reference to this International Standard, i.e. ISO 8496;b) identification of the test piece;c) dimensions of the test piece;d) result of the test.2 ISO 2013 All rights reservedCopyright European Committee for Standardization Provided by IHS under l
