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
