CSA MSE-73

1.1 This Technical Information Letter (TIL) contains construction, marking and test requirements for SDR 26, 28, 35, and 41 PSM type polyvinylchloride (PVC) perforated sewer pipe. Notes: 1) Industrial waste disposal lines should be installed only with the approval of the authority having jurisdiction because chemicals not commonly found in drains and sewers, and temperatures greater than 60 °C, can be encountered. 2) 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. 3) See the definition of "PSM" in Clause 3.1 of CSA B181.0. 1.2 Pipe manufactured to this Standard can have multilayer construction, and the middle layer can have reprocessed-recycled content. Note: In this Standard, the term "multilayer" refers to pipe having three layers.
