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.
