Bidet — a fixture with a hot and cold water supply intended for genital and perineal hygiene. Defect — Blemish — a dent, depression, or raised portion on the visible stainless steel surface of a fixture. Crack — a fracture in the surface or substrate material of a fixture. Die mark — a visible scoring of the stainless steel surface of a fixture. Pinhole — a hole in the stainless steel surface of a fixture whose largest dimension is 1.5 mm (0.06 in) or less. Wrinkle — a corrugation in the stainless steel surface of a fixture that is visible or can be felt. Fitting — a device that controls and guides the flow of water. Note: See ASME A112.18.1/CSA B125.1 and CSA B125.3 for definitions of specific types of fittings. Fixture — a device that receives water, waste matter, or both and directs these substances into a drainage system. Note: See ASME A112.19.2/CSA B45.1 for definitions of specific types of fixtures. Flange — a) the flat area on the front or sides of a compartment in a sink or lavatory; or b) the raised vertical section for retaining water in a tub or shower base. Flat-rim sink (rim-back sink) — a single- or double-compartment sink with flanges on all sides but no back ledge (ledge-back). Flood level — the level at which water will overflow a fixture. Flushometer valve — a flushing device attached to a pressurized water supply pipe that, when actuated, opens the pipe for direct flow into the fixture at a rate and in a quantity that enables proper operation of the fixture. The valve then gradually closes to provide trap reseal in the fixture and avoid water hammer. Note: The pipe to which the flushometer valve is connected should be large enough to enable it to deliver water at a sufficient rate of flow for flushing. Horizontal surface — a surface forming an angle with the horizontal of less than 45°. Integral rim — a mounting rim that is an integrally formed part of a sink flange and has clamp-down devices for attaching the sink to the countertop. Lavatory — a washbowl or basin. Ledge — the flat area of a sink or lavatory on which supply fittings are normally mounted. Ledge-back sink — a single- or double-compartment sink with a ledge along the back that has openings for mounting supply fittings. Mirror finish — a highly reflective finish with no visible polishing lines. Rim — the unobstructed open edge of a fixture. Satin finish — a surface with a soft sheen consisting of fine, regular polish lines in a uniform pattern.
Urinal — a fixture that receives only liquid body waste and conveys the waste through a trap into a drainage system. Vertical surface — a surface forming an angle with the horizontal of 45 to 90°. Water closet — a fixture with a water-containing receptor that receives liquid and solid body waste and on actuation conveys the waste through an exposed integral trap into a drainage system. 4 General requirements 4.1 Materials With the exception of laboratory sinks, which shall be made of type 316 stainless steel alloy, stainless steel plumbing fixtures shall be made of type 201, 202, 301, 302, 304, 316, or 430 stainless steel alloys. Note: These stainless steel alloy types are specified in ASTM A240/A240M. 4.2 Stainless steel thickness 4.2.1 Lavatories and sinks 4.2.1.1 General The thickness of stainless steel sheet for lavatories and kitchen, bar, laboratory, laundry, and utility sinks shall comply with Clause 4.2.1.2 (before drawing) or 4.2.1.3 (after drawing). 4.2.1.2 Before drawing The minimum thickness shall be based on bowl depth as specified in Table 1. 4.2.1.3 After drawing The minimum thickness after fabrication shall be as follows: a) vertical surfaces: 0.559 mm (0.022 in); b) corners: 0.508 mm (0.020 in); and c) horizontal surfaces: 0.635 mm (0.025 in). For Items a) and b), the thickness shall be determined by taking the average of six measurements of surface or corner thickness. For Item c), thickness shall be determined by taking the average of three measurements from the bottom of the fixture and three from the flat surfaces of the flange. 4.2.2 Other fixtures The thickness of stainless steel sheet for fixtures not specified in Clause 4.2.1.1 shall be determined in accordance with Clause 4.2.1.3. 4.3 Tolerances Unless otherwise specified in this Standard, the tolerance on dimensions of 200 mm (8 in) and greater shall be ± 3%. The tolerance on dimensions less than 200 mm (8 in) shall be ± 5%. In this Standard, dimensions specified as “minimum” or “maximum” shall not be reduced below the specified minimum or increased above the specified maximum by application of a tolerance. If a dimensional range is specified and the word “minimum” or “maximum” does not appear, the upper and lower limits shall not be considered critical and the appropriate tolerance shall apply.
