5.1 This is not a routine test. The values recorded are applicable only to the pipe being tested and at the time of testing.

1.1 This practice covers procedures for testing installed non-perforated, gasketed corrugated high-density polyethylene (HDPE) and corrugated polypropylene (PP) pipelines using either water infiltration or exfiltration acceptance limits to demonstrate the integrity via the level of leakage of the installed materials, construction procedures and installation qualityvia the level of leakage. Pipe to be tested under this practice shall include corrugated HDPE and PP drainage pipe meeting the requirements of AASHTO M 252, AASHTO M 294 and Specifications F2306/F2306M, F2736, F2762, F2763, F2764/F2764M, and F2947/F2947M.

1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are mathematical conversions to inch-pounds, which are provided for informational purposes only and are not considered standard.

1.3 This test method shall be performed on lines after all connections and service laterals have been plugged and braced adequately to withstand the test pressures. The time between completion of the backfill operations and testing shall be specified by the approving authority.

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.
