Preface This is the third edition of ASME A112.19.3/CSA B45.4, Stainless steel plumbing fixtures. It supersedes the previous edition published in 2017. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was prepared by the ASME A112.19.3 Project Team on Stainless Steel Plumbing Fixtures, under the jurisdiction of the ASME A112 Standards Committee on Plumbing Materials and Equipment and the CSA Technical Committee on Plumbing Fixtures. The ASME A112 Standards Committee operates under the jurisdiction of the ASME Board on Standardization and Testing and the CSA Technical Committee operates under the jurisdiction of the CSA Strategic Steering Committee on Construction and Civil Infrastructure. This Standard has been formally approved by the ASME Standards Committee and the CSA Technical Committee. This Standard was approved as an American National Standard by the American National Standards Institute on May 17, 2022. This Standard has been developed in compliance with the Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 1.1 This Standard covers plumbing fixtures made of stainless steel alloys 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) lavatories; e) shower bases; f) sinks: i) bar sinks; ii) clinic sinks; iii) kitchen sinks; iv) laboratory sinks; v) laundry sinks; vi) service sinks; and vii) utility sinks. g) urinals; and h) water closets. 1.3 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; 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. 1.4 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. All references to gallons are to U.S. gallons. For information on the unit conversion criteria used in this Standard, see Annex A.
