0 Introduction


This harmonized Standard was developed in response to an industry request for a Standard for evaluation of aluminum and copper plumbing fixtures that would be acceptable for use in both Canada and the United States. Standards for plumbing fixtures made of other materials are also available or under development.


Harmonization activities for plumbing fixtures standards were undertaken in 2005 by a Joint Harmonization Task Group (JHTG) on Plumbing Fixtures, in which the CSA and IAPMO plumbing fixtures committees were equally represented. The responsibility for procedural matters and final approval of technical content was assumed by technical committees at higher levels within each SDO.

1 Scope


This Standard covers aluminum and copper plumbing fixtures and specifies requirements for materials, construction, performance, testing, and markings of these fixtures.


This Standard covers the following plumbing fixtures:

(a) bathtubs and combination tub/showers;

(b) lavatories;

(c) shower bases and shower stalls; and

(d) sinks:

(i) bar sinks;

(ii) kitchen sinks;

(iii) laundry sinks;

(iv) service sinks; and

(v) drinking fountains.


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



SI units are the units of record in Canada. In this Standard, the inch/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.

All references to gallons are to U.S. gallons.

For information on the conversion criteria used in this Standard, see Annex A.
