Linear misalignment and angular distortion of the test pieces should be kept to a minimum and recorded on the test report.5.2 Test

38、 specimens5.2.1 DimensionsThe dimensions of the test specimens shall be in accordance with Figures 3 and 5. The weld axis shall remain perpendicular to the longitudinal direction of the specimen.5.2.2 MarkingEach test specimen shall be marked to identify its exact location in the test piece. If requ

39、ired by the relevant application standard, the direction of working (e.g. rolling or extrusion) shall be marked.5.3 Heat treatment and/or ageingNo heat treatment shall be applied to the welded joint or to the test specimen unless it is specified or permitted by the relevant application standard deal
