1.1 This practice covers procedures for testing concrete pipe sewer lines, when using the low-pressure air test method to demonstrate the integrity of the installed material and the construction procedures. This practice is used for testing 4 to 24-in. circular concrete pipe sewer lines utilizing gasketed joints.

1.2 This practice may also be used as a preliminary test to enable the installer to demonstrate the condition of the line prior to backfill.

1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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 (see Section 6, Safety Precautions).

1.4 A complete metric companion to Practice C924 has been developed-C924M; therefore, no metric equivalents are presented in this practice.

Note 1-Air test criteria presented in this practice are similar to those in general use. The test and criteria have been used widely and successfully in testing smaller diameter pipe, but additional data are required to confirm the safety and applicability or develop criteria for pipe larger than 24 in. in diameter. Larger pipe may be accepted more conveniently by visual inspection and individual joint testing. Note 2-It should be understood that no correlation has been found between air loss and water leakage.
