Hydrostatic Test
The pipe shall withstand the hydrostatic test without leakage through the weld seam or the pipe body
Jointers need not be hydrostatically tested, providedthat the portions of pipe used in marking the jointers were successfully hydrostatically tested prior to the joining operation.
Traceablity:
For PSL 1 pipe, the manufacturer shall establish and follow documented procedures for maintaining:
The heat identity until each related chmical tests is performed and conformance with the specified requirements is shown
The test-unit identity until each related mechanical tests is performed and conformance with the specified requirements is shown
For PSL 2 pipe, the manufacturer shall establish and follow documented procedures for maintaining the heat identity and the test-unit identity for such pipe. Such procedures shall provide means for tracing any length of pipe to the proper test unit and the related chemical test results.
