Over deze norm
1.1 This practice covers procedures for testing installed non-perforated, gasketed corrugated high-density polyethylene (HDPE) 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 drainage pipe meeting the requirements of AASHTO M 252, AASHTO M 294 and Specification F2306/F2306M.
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.
