About This Item


Full Description

This is the second edition of CSA B45.5/IAPMO Z124, Plastic plumbing fixtures. It supersedes the previous edition published in 2011.

This Standard replaces

a) CAN/CSA-B45.5-02, Plastic plumbing fixtures;

b) IAPMO/ANSI Z124.1.2-2005, Plastic Bathtub and Shower Units;

c) IAPMO/ANSI Z124.3-2005, Plastic Lavatories;

d) IAPMO/ANSI Z124.4-2006, Plastic Water Closet Bowls and Tanks;

e) IAPMO/ANSI Z124.6-2007, Plastic Sinks; and

f) IAPMO/ANSI Z124.9-2004, Plastic Urinal Fixtures.

This Standard covers plastic plumbing fixtures and specifies requirements for materials, construction, performance, testing, and markings.

This Standard covers the following plumbing fixtures:

a) bathtubs and combination tub/showers;

b) lavatories;

c) shower bases and shower stalls;

d) sinks:

i) bar sinks;

ii) kitchen sinks;

iii) laundry sinks; and

iv) service sinks;

e) urinals; and

f) water closets.

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.

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.
