1.2
Plumbing waste fittings are covered by ASME Al 12.1 8,2/CSA 8125.2.
1.3
Other devices, e.g.. temperature-actuated In-line mixing valves and flexible connectors under continuous pressure, are covered by CSA 8125.3 or other plumbing product Standards
This Standard does not apply to pipes and tubes or pipe and tube fittings.

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 pan of the table or figure and may be written as requirements.
1.6
The values stated In either SI (metric) or yard/pound units are to be regarded as the standard. SI units are the units of record In Canada
In this Standard, the yard/pound units are shown in parentheses. The values stated in each measurement system are equivalent in application; however, each system is to be used independently. Combining values from the two measurement systems can result In non-conformance with this Standard.
