0.1 psi and an accuracy of 0.0625 psi. The test procedure is as follows

(1) Add air slowly to the section of system being tested until the internal air pressure is

raised to 4 psi greater than the average back pressure due to groundwater. When

acceptable to the engineer, 5 psi may be used to account for groundwater.

(2) After the test pressure is reach, allow at least 2 minutes for the air temperature to

stabilize, adding only the amount of air required to maintain pressure.

(3) After the temperature stabilization, disconnect the air supply.

(4) Monitor the pressure gauge for the minimum time required. There will be no internal air

pressure drop allowed with 3034 PVC pipe. In no case shall length of test (T) be less

than the following chart.
