22、has been increased by30 %. The flared specimen shall not exhibit cracking throughthe wall.5.2 Hydrostatic TestEach pipe or tube shall be tested bythe manufacturer to an internal hydrostatic pressure of 1000 psi(6.9 MPa) provided that the fiber stress, calculated from thefollowing equation, does not
23、exceed the allowable fiber stressfor the material:P 5 2St/D (1)where:P = hydrostatic test pressure, psi (MPa),S = allowable fiber stress, for material in the condition(temper) furnished as specified in the product specifi-cation (S is calculated as the lower of23 of the specifiedminimum 0.2 % offset

34、libration defect shall besubject to rejection.5.3.4.1 Test signals produced by imperfections that cannotbe identified or produced by cracks or crack-like imperfectionsshall result in rejection of the pipe or tube, subject to reworkand retest.5.3.4.2 If the imperfection is judged as not fit for use,
35、thetube shall be rejected, but may be reconditioned and retestedproviding the wall thickness requirements are met. To beaccepted, retested material shall meet the original electric testrequirements.5.3.4.3 If the imperfection is explored to the extent that itcan be identified, and the pipe or tube i
36、s determined to be fit foruse, the material may be accepted without further testing,providing the imperfection does not encroach on minimumwall thickness requirements.5.4 When specified by the purchaser, a nondestructiveelectric test, in accordance with Practices E213, E426,orE571,may be used for se
