ASME A112.19.1-2008 pdf – Enamelled cast iron and enamelled steel plumbing fixtures.
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 0.13 mm (0.005 in) for steel.
4.4.5 Surface treatments
Before they are enamelled, surfaces shall be treated with ground coat. Alter 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 fitting openings and drainage
(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.
Except when proprietary (i.e., non-standard) waste fittings are provided by the manufacturer, the dimensions of waste outlets shall be as shown in Figure 1.
Factory-supplied waste fittings shall comply with ASME Al 12.1 8.2/CAN/CSA-Bl 25.2.
22.214.171.124 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.
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
When provided, openings and mounting surfaces for lavatory and sink supply fittings shall be as shown In Figures 2 to 6, except when proprietary (i.e., non-standard) supply fittings are provided by the manufacturer.
Factory-supplied lavatory and sink supply fittings shall complywith ASME Al 12.18.1ICAN/CSA-B125.1.
Mounting surfaces for supply fittings that rely on an air gap for backfiow protection shall be not more than 13 mm (0.5 in) below the flood level rim.
Note: Core should be token to ensure that the minimum owgop specified In 4SME Al 12.18. 1/CAN/CSA-8125. 1 or In the applicable plumbing code is not compromised when supply linings ore installed on fixtures with mount wig suit oces below the flood level rim.
4.7 Additional requirements for bathtubs and shower bases
4.7.1 MInimum dimensions for bathtubs
The minimum dimensions for bathtubs shall be as shown in Figure 7.
4.7.2 Slope to the waste outlet
Bathtubs and shower bases shall have a maximum slope of 4% to the waste outlet.
Note: There should be a minimum slope of 1% to the waste outlet.
Bathtubs intended for installation against a wall shall incorporate a continuously raised flange or bead extending at least 8 mm (0.3 in) above the rim,
Shower bases intended for installation against a wall shall incorporate a continuously raised flange or bead extending at least 25 mm (1.0 in) above the exposed sides and back.
The raised flange shall be
(a) integral with the bathtub or shower base;
(b) added to an island tub or shower base in the faclo#y; or
(c) field installed using a flange kit that complies with Clause 5.4. Fixtures using field.installed flanges shall be marked in accordance with Clause 6.3 and shall include all necessary parts and fasteners.
4.7.4 Slip-resistant surfaces
The slip-resistant surfaces of bathtubs and shower bases shall comply with ASTM F 462 and have the dimensions shown in Figure 8.
4.8 Additional requirements for drinking fountains
Drinking fountains shall
(a) include a supply fitting, which shall be at least 25 mm (1.0 in) above the flood level rim; and
(b) comply with the dimensions shown in Figure 9.
Note: Drinking fountain sp4’ fittings ore also known as drinking fountain bubblers.
Factory.supplied drinking fountain supply fittings shall comply with ASME Al 12.18.1 /CAN/CSA-Bl 25.1, including the toxicity requirements.
4.9 Accessible design fixtures
Fixtures designed to be accessible shall comply with the dimensional requirements specified in
CAN/CSA B651 or ICC/ANSI Al 17.1.
