Significance and Use
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 test method covers procedures for testing concrete pipe sewerlines, when using the negative air pressure (vacuum) test method to demonstrate the integrity of the installed material and the construction procedures. This test method covers testing of 100 to 900-mm diameter circular concrete pipe sewerlines utilizing gasketed joints.
Note 1—The user of this specification is advised that methods described in this test method may also be used as a preliminary test to enable the manufacturer or installer to demonstrate the condition of sewer pipe prior to delivery or backfill. Minimum test times presented in Table 1 are for pipelines. Holding times for testing an individual pipe may have to be increased to allow for the accumulation of leakage when the tested pipe are incorporated into a continuous pipeline.
Note 2—The user of this test method is advised that the negative air pressure (vacuum) test criteria presented in this test method are similar to those in general use. The test and criteria have been used widely and successfully in testing smaller diameter pipe. Larger pipe will be accepted more conveniently by visual inspection and individual joint testing.
Note 3—The user of this test method is advised that no correlation has been found between loss of vacuum and water leakage.
1.2 This test method is the SI companion to Test Method C 1214.
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. See Section 6 for specific safety precautions.
