22、ecifies 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 assess the ductility of tubes.The ring tensile test is applicable to tubes having an outside diameter exceeding 150 mm

23、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 circumferential direction until fracture occurs.3 ApparatusUse two circular pins, of equal diameter with parallel axes, and movable in

24、 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 inside diameter of the tube allows, should be at least 3 times the wall thickness of the tube to be tested (see Figure 1)

If the

26、thickness 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 req

27、uirements.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 m

28、oving the 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 spec

29、ified, the 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

30、 report shall 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 reservedBS EN ISO 8496:2013This page deliberately left blankThis page
