8 PRESSURE TESTING

8.1 Flange Test

Flanges are not required to be pressure tested.

8.2 Flanged Fitting Test

8.2.1 Shell Pressure Test.  Each flanged fitting shall be given a shell pressure test.

8.2.2 Test Conditions.  The shell pressure test for flanged fittings shall be at a pressure no less than 1.5 times the 38C (100F)pressure rating rounded off to the next higher 1 bar (25 psi)increment.

8.2.3 Test FLuid.  The pressure test shall be made using water,which may contain a corrosion inhibitor or kerosene as the test fluid.Other suitable test fluids may be used provided their viscosity is no greater than that of water. The test fluid temperature shall not exceed 50C(125F).

8.2.4 Test Duration.  The test duration shall be as follows:

8.2.5 Acceptance.  No visible leakage is permitted through the pressure boundary wall.
