LOW PRESSURE AIR TEST FOR GRAVITY SArIITAIA _ ft S31 �
Test Procedures : Each section of sewer shall be tested between successive manhole Z�-�,,
Air shall be introduced into the pipeline until 4.0 psi gauge pressure has been reach ,r At that time the flor
shall be reduced and the internal air pressure shall be maintained between 3.5 and 4.5 psi gairat least two (utes
to allow the air temperature to come to equilibrium with the temperature of the pipe walls. Pres ilgj1 be
constantly monitored by a gauge and hose arrangement separate from the hose used to introduce air mlb ei-m'e. Pressure
in the pipe shall not be allowed to exceed 5 psi.
After the temperature has stabilized and no air leaks at the plugs have been found, the air pressure shall be used to
determine that time lapse required for the air pressure to drop to 2.5 psi gauge.
If the time lapse required for the air pressure to decrease from 3.5 to 2.5 psi exceeds that shown in the following
table, the pipe shall be presumed to be within acceptable limits for leakage.
If the time lapsed is less than that shown in the table, the contractor shall make corrections to reduce the leakage to
acceptable limits.
