For small diameter pipes, the test ma

If thermal cutting or other cutting methods which could affect the cut surfaces are used to cut the test specimen from the weld

31、ed 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 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 therm

32、al cutting are excluded, and only machining (e.g. sawing or milling) shall be used.5.5 Machining5.5.1 GeneralThe tolerances specified 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 th

33、e welded joint see Figure 1 a). When a relevant application standard requires testing of the full thickness 30 mm, several test specimens may be taken to cover the full thickness of the joint see Figure 1 b).
