The piping shall be tested at 1 1/2 times the maximum working pressure applicable to that part of the piping system but at a pressure not less than the test pressure required for the storage tank. The minimum pressure for testing tanks shall be 1 1/2 times the maximum working pressure applicable to the tank but in no case less than 25 psig (172.4 kPag), except as provided for containers 6 gallons (22.7 L) or less in capacity as provided for in Section 1305.14.4 Exception 3. The hydrostatic pressure shall be maintained until all joints and connections have been visually inspected for leaks, but in no case for less than 1/2 hour. The tank shall not show any permanent deformation as a result of the test. A record shall be kept of the pressure tests showing the name of the contractor and the pressures at which the piping and the tank were tested.\n\n1308.3.
