This is not a routine test. The values recorded are applicable only to the sewer being tested and at the time of testing.

1.1 This practice covers procedures for testing the joints of installed precast concrete pipe sewer lines, when using either air or water under low pressure to demonstrate the integrity of the joint and the construction procedures. This practice is used for testing 675-mm and larger diameter precast concrete sewer lines utilizing rubber gasket sealed joints.

Note 1—The user of this test method is advised that methods described herein may also be used as a preliminary test to enable the manufacturer or installer to demonstrate the condition of sewer pipe prior to delivery.

1.2 This practice is the SI companion of Practice C 1103.

Note 2—The owner shall specify the following: who will conduct, observe, and furnish labor, material, and measuring devices and pay for the tests; who is responsible for determining local ground conditions; and whether an air or water test is to be used.

Note 3—The user of this practice is advised that test criteria presented in this practice are similar to those in general use. Pipe 600-mm diameter and smaller shall be accepted by infiltration or exfiltration testing utilizing Practice C 969M or by low pressure air testing utilizing Practice C 924M. Pipe greater than 600-mm diameter shall be accepted by infiltration or exfiltration testing utilizing C 969M.

Note 4—The user is advised that no correlation has been found between air loss and water leakage.
