3 Definitions
The following definitions apply in this Standard:
Air gap — the unobstructed vertical distance, through the open atmosphere, between the lowest opening of a water supply and the flood level of the fixture.
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: S&t ASME Al 12.18. 1/C4N/CS.4-8125. I end CAN/C5A-8 125.3 for defwiitons of specific types o(fittings.
Fixture – a device that receives water, waste matter, or both and directs these substances into a drainage system.
Note: See AWE A 112.1 9.2/CiA 8-43.1 for ddinitons 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.
Fiushometer 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 wiPich the fluthometer vaiw is connected should be Jorge enough to enable to delñ’er water at a sufficient rote of flow for flushing.
Horizontal wrface — a surface forming an angle with the horizontal of less than 450 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 lavatoy 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.
