1.1 This test method covers procedures for testing of precast concrete pipe sections, prior to delivery, where maximum field leakage rates are specified.
1.2 Tests described in this standard are intended to be used at the point of manufacture of the concrete pipe and are not intended for testing installed pipe (for field tests see Practices C 924, C 969, and C 1214). The user of this specification is advised that individual or multiple pipe sections may be tested for the purpose of testing the pipe barrel and additionally the joints in straight alignment when multiple pipe sections are tested.
1.3 The two leakage rates shown, which were used in calculating the test times, were chosen based on two generally accepted field air and vacuum test criteria. Test times are based on leakage rates and therefore are proportional only to the pipe diameter and are constant for any length of test pipe or pipeline.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
Note 18212;The availability of this test procedure for concrete pipe varies from location to location. Check with local supplier(s) for availability and recommendations.
1.5 This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish the appropriate safety and health practices and to determine the applicability of regulatory limitations prior to its use. See Section 6 for specific safety precautions.
