|
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 4 to 36-in. diameter circular concrete pipe sewerlines utilizing gasketed 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 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: Test times tabulated and the rate of air loss in this
standard are based on successful testing of installed pipelines.
However, since air and water have different physical properties,
retests of some pipelines not meeting field air tests have been
successful when tested with water.
1.2 This test method is the inch-pound companion to Test Method C1214M; therefore, no SI equivalents are presented in the test method. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
