This Standard specifies requirements for SDR 26, 28, 35, and 41 PSM type polyvinylchloride (PVC) perforated and non-perforated sewer pipe and fittings.

Notes:

Industrial waste disposal lines should be installed only with the approval of the authority having jurisdiction because Cchemicals not commonly found in drains and sewers, and temperatures greater than 60 °C, can be encountered in industrial waste disposal lines. Consult with the authority having jurisdiction before installation.

Nominal pipe size is indicated by an NPS designation and actual dimensions are given in millimetres. For example, an NPS-10 pipe will be nominally 10 in in diameter.

Pipe manufactured to Tthis Standard coversmay have multilayer pipeconstruction, and the middle layer canmay have reprocessed-recycled content.

Note: In this Standard, the term “multilayer” refers to pipe having three layers.

1.3 Terminology
