32、 this test. Lengths with discontinuities indicated by the tester may, at the option of the manufacturer, bereexamined or retested to determine whether the discontinuity is cause for rejection. Signals that are found to have been causedby minor mechanical damage, soil, or moisture shall not be cause
33、for rejection provided the pipe or tube dimensions are still withinthe prescribed limits and the pipe or tube is suitable for its intended application.10.1.2 Hydrostatic TestEach length shall stand, without showing evidence of leakage, an internal hydrostatic pressuresufficient to subject the materi
34、al to a fiber stress of 7000 psi (48 MPa) (48 MPa) determined by the following equation for thinhollow cylinders under internal pressure.
