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.

1.2 This practice is the metric companion of Practice C1103.

Note 1--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 2--Test criteria presented in this practice are similar to those in general use. Pipe 600-mm diameter and smaller may be accepted by infiltration or exfiltration testing utilizing Practice C969M or by low pressure air testing utilizing Practice C924M. Pipe greater than 600-mm diameter may be accepted by infiltration or exfiltration testing utilizing C969M.

Note 3--It should be understood that there is no correlation between air loss and water leakage.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
