44、1 GeneralThe examination length, Lf, and area, Af, and the number of test specimens shall be specified by the application standard or by agreement between the contracting parties. Welded joints in plates shall be cut transversely to the welded joint in test specimens of approximately equal weld leng
45、th. The weld axis shall remain in the middle of the test specimen for butt welds.For welded joints in pipe, unless otherwise specified in the application standard or by agreement between the contracting parties, the test piece shall provide at least two test specimens.When carrying outbend tests, eq
46、ual numbers of specimens shall be tested with the root in tension and the face in tension. If the pipe diameter is too small for removing the required number of test specimens, additional test pieces shall be welded.7.2 MarkingEach test piece shall be marked to identify its exact location in the man
47、ufactured product or in the joints from which it has been removed.When removed from the test piece, each test specimen shall be marked.7.3 Extraction7.3.1 GeneralThe extraction method shall avoid the introduction of detrimental thermal or mechanical effects.In general, a portion 25 mm from both ends
48、 of the test welds shall be discarded, unless information about the ends of the welds is required (e.g. start/stop imperfections).6 ISO 2017 All rights reservedBS EN ISO 9017:2018ISO 9017:2017(E)7.3.2 SteelsThe test specimens shall be cut by thermal cutting or by mechanical means.7.3.3 Other metalli
