time the flow .of air shall be. reduced and the internal air pressure shall be maintainedwa��3� and 4.5
psi gauge for at least two :(2) minutes to allow the air temperature to come to equilibri with the
temperature of the pipe walls. Pressure in the pipe shall be constantly monitored by a age and hose Q�
arrangement separate from the hose used to introduce air into the line. Pressure in the pi )Y gib
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. ,
