This is the first edition of ASME A112.18.1/CSA B125.1, Plumbing supply fittings. This joint Standard was developed in response to an industry request for a Standard for testing plumbing supply fittings that would be acceptable in both Canada and the United States. Its coverage is restricted to devices located between the supply line stop and the terminal fitting. Plumbing waste fittings are covered by ASME A112.18.2/CSA B125.2, Plumbing waste fittings. Devices not covered by this Standard or by ASME A112.18.2/CSA B125.2, e.g., temperature-actuated in-line mixing valves and flexible connectors under continuous pressure, are covered by CSA B125.3, Plumbing fittings. The technical content of Clause 5.10 of this Standard was developed jointly by the American Association of Sanitary Engineering (ASSE) and CSA.
1.1 This Standard applies to plumbing supply fittings and accessories located between the supply line stop and the terminal fitting, inclusive, as follows:
(a) automatic compensating valves for individual wall-mounted showering systems;
(b) bath and shower supply fittings;
(c) bidet supply fittings;
(d) clothes washer supply fittings;
(e) drinking fountain supply fittings;
(f) humidifier supply stops;
(g) kitchen, sink, and lavatory supply fittings;
(h) laundry tub supply fittings;
(i) lawn and sediment faucets;
(j) metering and self-closing supply fittings; and
(k) supply stops.
1.2 Plumbing waste fittings are covered by ASME A112.18.2/CSA B125.2.
1.3 Other devices, e.g., temperature-actuated in-line mixing valves and flexible connectors under continuous pressure, are covered by CSA B125.3 or other plumbing product Standards.
1.4 This Standard does not apply to pipes and tubes or pipe and tube fittings.
1.5 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.
1.6 The values stated in either SI (metric) or yard/pound units are to be regarded as the standard. 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 US gallons. For information on the conversion criteria used in this Standard, see Annex A.
