The longitudinal axis of the test piece shall be located at mid-section thickness. 6.1.3.3 Identif trtwn of test piecas Each test pie
18、ce shall be marked in such a manner that it is possible to identify the inspection lot from which it was taken, and, if required, its location and orientation in the product. If a test piece is marked by stamping, this shail not be in a place or manner which may interfere with subsequent testing. Wh
19、ere it is not convenient to mark a test piece, an identification tag may be attached. 6.1.3.4 Machining Any machining necessary shall be ded out in such a manner that it does not change the characteristics of the metal in the test piece. 6.1.3.6 Number of test pieces One test piece shall be taken fr
