Apply test pressure slowly, and once the test pressure has been reached,
allow the pressure to stabilize, without adding additional pressure. This
may take 2 to 3 hours.
Once pressure has stabilized, add additional water to achieve the test
pressure and begin the test.
After 1 hour, additional water shall be added to return to the test
pressure. If the volume of water required to achieve the test pressure
after 1 hour is less than shown in the table, then the pipe has passed the
pressure test.
The total test time, including the initial pressurization, initial expansion
and time at test pressure, shall not exceed eight hours. If the test is not
completed within that time, the test pressure shall be removed for at least
eight hours, prior to performing the test again.
If pressure test is not accepted, correct leaks or defects in the pipe and
retest.
Remove temporary sectionalizing devices after tests are complete.
