|
1.1?This practice covers procedures for testing single joints of thermoplastic pipe for gravity flow (non-pressure) sewer lines, when using either air or water under low pressure to demonstrate the integrity of the joint. This practice is used for testing 27 in. (675 mm) and larger inside diameter PVC (Polyvinyl Chloride), HDPE (High Density Polyethylene) and PP (Polypropylene) sewer lines utilizing flexible gasketed joints with elastomeric seals, Specification F477. 1.2?This practice is used for assessing the watertight integrity of a joint at the time of the test. It is not a pipeline acceptance test as it does not evaluate the integrity of the pipe barrel or any long-term pipeline deformation effects from backfill settlement Note 1:?The user of this practice is advised that methods
described herein is typically used as a preliminary test to enable
the installer to demonstrate the integrity of a sewer pipe joint
prior to placement of final backfill. Such testing after initial
backfill can detect if a gasket has rolled or dirt was pushed into
the joint during the mating of the pipe. Repair of these types of
installation problems can be done very quickly and effectively
prior to final backfill, but once final backfill is placed, repairs
are very difficult and costly.
Note 2:?This practice may be used at any time to check the
integrity of a joint prior to acceptance testing or to locate a
leaking joint when a pipeline fails a hydrostatic
infiltration/exfiltration test, vacuum test or air pressure test
during any time of the installation and acceptance
process.
Note 3:?The user of this practice is advised that no
correlation has been found between air loss and water
leakage.
1.3?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4?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. 1.5?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. |
