4 Testing equipment
The test machine is capable of flattening the test piece to the prescribed distance H between two plane, parallel, rigid platens.
The width of the platens shall exceed the width of the test piece after flattening, i.e. at least 1,6 D, and the length of the platens shall extend over the whole length of the test piece.
5 Test piece
5.1 The length of a test piece shall be no less than 10 mm and no more than 100 mm. The edges of the test piece may be rounded by Illing or chamfered by other methods.
NOTE Non-rounded or non-chamfered edges are permissible if the test result meets the test requirements.
5.2 When the test is carried out on the end of a full-length tube, the tube shall be cut at right angles to the axis of the tube to a depth of at least 80% of the tube outside diameter. The cut shall be at a distance from the end of the tube eqLlal to the length of the test piece.
6 Procedure
61 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.
6.2 Place the test piece between two platens.
6.3 Ensure that the weld of the welded tubes is in a position as required by the relevant product standard.
6.4 Flatten the test piece by moving the platens in a direction perpendicular to the longitudinal axis of
the tube.
6.5 In case of dispute, the rate of movement of the platens shall not exceed 25 mm/mm.
6.6 Interpretation of the flattening test shall be carried out in accordance with the requirements of the relevant product standard. When these requirements are not specified, the test piece shall be considered to have passed the test if no cracks are visible without the use of magnifying aids. Slight cracking at the edges shall not be considered a cause for rejection.ISO 8492-2013 pdf free download.
