23、ndard is based on ISO 8495:1986 Metallic materials Tube Ring expanding test which has been editorially changed in the light of the comments received. The data to be reported in clause 8 “Test report”, when this is required, has been increased. The usage of symbols has been aligned with the requireme
24、nts of ISO 3545-1:1989.1 ScopeThis European Standard specifies a method for a ring expanding test on tubes, that is used to reveal defects both on the surfaces and within the tube wall by expanding the test piece using a drift until fracture occurs. It may also be used to assess the ability of tubes
25、 to undergo plastic deformation.The ring expanding test is applicable to tubes having an outside diameter from 18 mm up to and including 150 mm and wall thickness from 2 mm up to and including 16 mm.2 Normative referenceThis European Standard incorporates by dated or undated reference, provisions fr
26、om other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendm
27、ent or revision. For undated references the latest edition of the publication referred to applies.ISO 3545-1:1989, Steel tubes and fittings Symbols for use in specifications Part 1: Tubes and tubular accessories with circular cross-section.3 PrincipleExpanding a ring cut from the end of a tube, over

31、face shall be of sufficient hardness, well polished and free from scores.6 Test piece6.1 The length of the test piece shall bebetween 10 mm and 16 mm. Test pieces shall betaken from the ends of deburred tubes as manufactured before they are cut to length. The rings shall be cut so that the planes of
32、 the end faces are parallel with each other and perpendicular to the axis of the tube.6.2 The edges of the test piece 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 requirements.6.3 When welded tubes are su
33、bjected to the test, the internal weld flash may be removed.7 Procedure7.1 In general, the test shall be carried out at ambient temperature within the limitsof 10 C to 35 C. The test carried out under controlled conditions shall be made at a temperature of (23 5) C.7.2 Before testing, the rings and
34、the mandrel may be lubricated. Rings of the same size and the same type of metal may be placed one on top of each other. The rings and the mandrel shall be concentric(see Figure 1).7.3 Force the conical mandrel into the rings until the required expansion is reached or the rings fracture.7.4 In cases
35、 of dispute, the rate of penetration of the mandrel shall not exceed 30 mm/s.Figure 1 Symbols for ring expanding testLicensed Copy: FELIX HERZING, TUV RHEINLAND BERLIN BRANDENBURG 5954918, 13 April 2004, Uncontrolled Copy, (c) BSI7.5 The relative expansion shall be calculated in accordance with the
36、relevant product standard.7.6 Interpretation of the ring expanding test shall be carried out according to the requirements of the relevant product standard. When these requirements are not specified, absence of surface and internal defects visible without the use of magnifying aids shall be consider
37、ed as evidence that the test piece passed the test.8 Test report8.1 A test report shall be provided when so specified in the relevant product standard.8.2 The test report shall include at least the following information:a) reference to this European Standard;b) identification of the test piece;c) di
