Draft Scope/Description:



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


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.


Pipe manufactured to this Standard may have multilayer construction, and the middle layer may have reprocessed-recycled content.

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


In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
