Canadian Standards Association International Association of Plumbing and Mechanical OfficialsPlastic plumbing fixturesMay 2012CSA B45.5-11/IAPMO Z124-2011Plastic plumbing fixtures0 Introduction0.1

18、This harmonized Standard was developed in response to an industry request for a Standard for evaluation of plastic 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.

19、0.2 Harmonization activities for plastic 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

20、 of technical content was assumed by technical committees at higher levels within each SDO.1 Scope1.1 This Standard covers plastic plumbing fixtures and specifies requirements for materials, construction, performance, testing, and markings.1.2 This Standard covers the following plumbing fixtures:(a)

21、 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.1.3 In this Standard, “shall” is used to express a requirement, i.e., a provision that the u

22、ser 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 requ

23、irements 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

24、 informative (nonmandatory) to define their application.1(Replaces p. 1, October 2011) Canadian Standards AssociationCSA B45.5-11/IAPMO Z124-2011 International Association of Plumbing and Mechanical OfficialsMay 20121.4 SI units are the units of record in Canada. In this Standard, the inch/pound uni

25、ts 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.
