36、lumbing fixtures American Society of Mechanical Engineers Canadian Standards AssociationASME A112.19.3-2008/CSA B45.4-08Stainless steel plumbing fixtures0 Introduction0.1 This harmonized Standard was developed in response to an industry request for a Standard for evaluation of plumbing fixtures that
37、 would be acceptable for use in both Canada and the United States. Harmonized Standards for plumbing fixtures made of other materials are also available or under development.0.2 The concept of harmonization for plumbing fixtures arose in the early 1990s, when a free trade agreement between Canada, M
38、exico, and the United States began to be discussed. Standards development organizations (SDOs) were at the forefront of these discussions and an opportunity soon arose for those SDOs involved in developing requirements for plumbing products to establish a process for harmonization. However, the effo
39、rt to develop a trinational Standard stalled until 2001, when ASME and CSA decided to develop a binational Standard for plumbing fittings.0.3 Harmonization activities for plumbing fixtures standards were undertaken in 2004 by a Joint Harmonization Task Group (JHTG) on Plumbing Fixtures, in which the
40、 ASME and CSA 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 Scope1.1 This Standard covers plumbing fixtures made of stainless steel alloys
41、 and specifies requirements for materials, construction, performance, testing, and markings.Note: The term “corrosion-resisting steel” is also applied to stainless steel.1.2 This Standard covers the following plumbing fixtures:(a) bathtubs;(b) bidets;(c) drinking fountains and water coolers;(d) lava
42、tories;(e) shower bases;(f) sinks:(i) kitchen and bar sinks;(ii) laboratory sinks;(iii) laundry sinks;(iv) service sinks; and(v) utility sinks;(g) urinals; and(h) water closets.1(Replaces p. 1, August 2008)July 2009 American Society of Mechanical EngineersASME A112.19.3-2008/CSA B45.4-08 Canadian St
43、andards Association1.3 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; “may” is used to express an option or
44、 that which is permissible within the limits of the standard; and “can” is used to express possibility or capability. 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 informativ
45、e 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.1.4 SI units are the units of record in Canada. In this Standard, the yard/po
46、und 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. g
47、allons.For information on the unit conversion criteria used in this Standard, see Annex A.2 Reference publicationsThis Standard refers to the following publications, and where such reference is made, it shall be to the edition listed below, including all amendments published thereto.CSA (Canadian St
