b. Successful completion of the leakage test shall have been achieved when the observed leakage is equal or less than the allowable leakage and no damage to piping and appurtenances has occurred.

E. Optional joint test:

1. When joint testing is allowed by note in the Piping Schedule, the procedure shall be as follows:
a. Joint testing will be allowed only for low head pressure piping. b. Joint testing does not replace and is not in lieu of any testing of the piping system or trust restraints.

2. Joint testing may be performed with water or air.

3. Joint test piping after completion of backfill and compaction to the top of the trench.

4. Joint testing with water:
a. Measure test pressure at the invert of the pipe. Apply pressure of 4 feet plus the inside diameter of the pipe in water column within 0.20 feet in water column.
b. Maintain test pressure for 1 minute.
c. Base the allowable leakage per joint on 80 gallons per inch nominal diameter, per mile of piping, per 24 hours equally distributed to the actual number of joints per mile for the type of piping.
d. Consider the pressure test to be complete when makeup water added is less than the allowable leakage.
e. Successful completion of the joint test with water shall have been achieved when the observed leakage is equal or less than the allowable leakage.

5. Joint testing with air:
a. Apply test pressure of 3 pounds per square inch gauge with a maximum variation of plus 0.20 and minus 0.00 pounds per square inch. b. Maintain test pressure for 2 minutes.
c. Consider the pressure test to be complete when the test pressure does not drop below 2.7 pounds per square inch for the duration of the test.
