ASTM-F3058 › Standard Practice for Preliminary Field Testing of Thermoplastic Pipe Joints for Gravity Flow (Non-Pressure) Sewer Lines
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
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 and health practices and determine the applicability of regulatory limitations prior to use.
Significance and Use
5.1 The values recorded are applicable only to the sewer joint being tested and at the time of testing.
