1.3 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; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability. 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. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.4 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 U.S. gallons. For information on the unit conversion criteria used in this Standard, see Annex A. 2 Reference publications This Standard refers to the following publications, and where such reference is made, it shall be to the edition listed below, including all amendments published thereto.

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: See ASME A112.18.1/CAN/CSA-B125.1 and CAN/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.
