Flattening Tests12.1 Although testing is not required, pipe shall be capableof meeting the flattening test

36、 requirements of SupplementaryRequirement S3, if tested.13. Hydrostatic Test13.1 Except as allowed by 13.2, 13.3, and 13.4, each lengthof pipe shall be subjected to the hydrostatic test withoutleakage through the pipe wall.13.2 As an alternative to the hydrostatic test at the option ofthe manufactur

42、orE570. In such cases,the marking of each length of pipe so furnished shall includethe letters “NDE.” It is the intent of this nondestructive electrictest to reject pipe with imperfections that produce test signalsequal to or greater than that produced by the applicablecalibration standard.14.2 Wher
