Die Annotation des Normtextes ASME A112.19.1:2024 :

Preface This is the fourth edition of ASME A112.19.1 • CSA B45.2, Enamelled cast iron and enamelled steel plumbing fixtures. It supersedes the previous editions published in 2018, 2013, and 2008. The following are major changes to this edition: a) addition of instructions for wall-mounted fixtures installations; b) addition of requirements for supply fittings; c) modifications to the shower base flanges requirements; and d) modifications to definitions in Clause 3. This harmonized Standard was developed in response to an industry request for a Standard for evaluation of plumbing fixtures that 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. 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 Standards Committee on Plumbing Materials and Equipment and the CSA Technical Committee on Plumbing Fixtures. The CSA Technical Committee operates under the jurisdiction of the CSA Strategic Steering Committee on Construction and Civil Infrastructure. This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard on February 13, 2024. This Standard has been developed in compliance with 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 Overview This Standard covers enamelled cast iron and enamelled steel plumbing fixtures, and specifies requirements for materials, construction, performance, testing, and markings. 1.2 Inclusions This Standard covers the following plumbing fixtures: a) bathtubs; b) drinking fountains and water coolers; c) lavatories; d) shower bases; and e) sinks: i) bar sinks; ii) clinic sinks; iii) kitchen sinks; iv) laboratory sinks; v) laundry sinks; vi) service sinks; and vii) utility sinks. 1.3 TerminologyIn 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 UnitsSI 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.
