0.2
The concept of harmonization for plumbing fixtures arose in the early 1990s, when a free trade agreement between Canada, Mexico, 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 effort 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 ASME and CSA plumbing fixtures committees were equally represented. The responsibility for procedural matters and final approval ot technical content was assumed by technical committees at higher levels within each SDO.
1 Scope
This Standard covers enamellea cast iron and enamelled steel plumbing fixtures and specifies requirements for materials, construction, performance, testing, and markings.
This Standard covers the following plumbing fixtures:
(a) bathtubs;
(b) drinking fountains and water coolers;
(c) lavatories;
(d) shower bases; and
(e) sinks:
(i) kitchen and bar sinks;
(ii) laundry sinks;
(iii) service sinks; and
(iv) utility sinks.
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;
4.4.4 Enamel thickness
The thickness of the enamel, measured on a flat surface at least 25 mm (1.0 in) from any edge of the fixture, shall be at least 0.64 mm (0.025 in) for cast iron and 0.1 3 mm (0.005 in) for steel.
4.4.5 Surface treatments
Before they are enamelled, surfaces shall be treated with ground coat. After enamelling, any surface subject to rework that exposes base metal shall be factory treated with rust inhibitor. All other steel surfaces shall be treated with at least one coat of filler, ground coat, or paint.
4.5 Waste fitting openings, drainage, and overflows
4.5.1 Waste fining openings and drainage
4.5.1.1
Fixtures shall
(a) have a waste fitting opening (outlet), the centre of which shall be located at the lowest point of the fixture; and
(b) drain to the waste outlet.
4.5.1.2
Except when proprietary (Le., non-standard) waste Fittings are provided by the manufacturer, the dimensions of waste outlets shall be as shown in Figure 1.
4.5.1.3
Factory-supplied waste fittings shall comply with ASME Al 12.18.2/CAN/CSA-B125.2.
4.5.2 Overflows
4.5.2.1 Provision and positioning
Overflows in lavatories and sinks may be provided at the option of the manufacturer. When overflows are provided, the manner in which they are positioned shall be at the option of the manufacturer.
4.5.2.2 Cleaning
When provided, overflows in sinks intended for food preparation (e.g., kitchen and bar sinks) shall not be concealed and shall be accessible for disassembly and cleaning after Installation.
4.6 Additional requirements for lavatories and sinks — Openings and mounting surfaces for supply fittings
4.6.1
When provided, openings and mounting surfaces for lavatory and sink supply fittings shall be as shown in
Figures 2 to 6, except when proprietary (Le,, non-standard) supply fittings are provided by the
manufacturer.
4.6.2
Factory-supplied lavatory and sink supply fittings shall comply with ASME Al 12.18.1 JCAN/CSA-Bl 25.1.
