    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

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
