3 Definitions The following definitions shall 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. Bathing surface — the portion of the sump of a bathtub on which, in accordance with common usage or design, a bather might step or stand while bathing or showering, and which is exclusive of ledges or rims. Defect — Blister — a hollow raised portion of the enamel surface of a cast iron or steel fixture. Large blister — a blister with a dimension greater than 6 mm (0.24 in). Medium blister — a blister whose largest dimension is between 1 and 6 mm (0.04 and 0.24 in). Small blister — a blister whose largest dimension is less than 1 mm (0.04 in). Chip — a blemish in the enamel exposing the undercoat or base metal. Crack — a fracture in the surface or the substrate material of a fixture. Craze (crazing) — separate and numerous hairlines in the enamel surface. Note: The lines can vary in length and can be up to several centimetres long. Hairline — a line within the enamel surface whose width does not exceed 0.05 mm (0.002 in). Dimple — a depression in the enamel surface. Lump — a raised portion of the enamel surface. Speck — a particle of foreign matter that produces areas of contrasting colour on the enamel surface of a fixture. Large speck — a speck with a dimension greater than 0.80 mm (0.031 in). Medium speck — a speck whose largest dimension is between 0.40 and 0.80 mm (0.01 6 and 0.031 in). Small speck — a speck whose largest dimension is greater than 0.25 mm (0.01 0 in) but less than 0.40 mm (0.01 6 in). Spot — an area of contrasting colour. Enamelled cast iron — a product cast from molten iron and coated with enamel fused to the metal (see Porcelain enamel). Note: The enamel coating is hard, glossy, opaque, and acid resistant and, in combination with the solid cast iron base, produces a rigid, durable product. Finish — the texture and condition of a surface (excluding colour). 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.
Flood level — the level at which water will overflow a fixture. Inspection window — a circular opening 76 mm (3.0 in) in diameter cut into a sheet of flexible material and used to count the number of defects in the opening (see Table 1 ). Lavatory — a washbowl or basin. Slab type lavatory — a lavatory that has the mounting surface for a faucet on top of a slab and does not have an elevated back. Ledge back — a flat elevated surface at the back of a lavatory, sink, or laundry sink, not more than 51 mm (2.0 in) higher than the rim and extending the full length of the fixture, on which the supply fitting can be mounted and small articles can be placed, or a similar construction with a centre panel suitable for mounting a supply fitting. Porcelain enamel — a vitreous or glossy inorganic coating that is bonded to the metal by fusion at high temperature. Rim — the unobstructed open edge of a fixture. Satin finish — a very smooth surface with low or dull reflective properties. Sheet steel — steel that can be satisfactorily porcelain enamelled, including the following: (a) special-purpose enamelling iron or steel of low metalloid and copper content that is specially manufactured and processed for the production of porcelain-enamelled fixtures; (b) special steels designed for porcelain-enamel application; and (c) cold-rolled steel. Shelf back — a flat elevated surface at the back of a lavatory, sink, or laundry sink more than 51 mm (2.0 in) higher than the rim and extending the full length of the fixture, on the top or front of which the supply fitting can be mounted and small articles can be placed, or a similar construction with a centre panel formed into the shelf suitable for mounting a supply fitting on either a horizontal or inclined surface. Spill level — the level at which water will flow out of one bowl into another bowl of the same fixture. Visible surface — a surface of a fixture that is readily visible to an observer in a normal standing position after the fixture is installed. Visible after installation — a surface that remains visible (not necessarily from a normal standing position) after the fixture is installed. 4 General requirements 4.1 General 4.1.1 Materials All materials shall be free from deficiencies that affect the fixture’s intended purpose. 4.1.2 Surface finish Fixtures shall have a surface free from defects to the extent specified in Table 1 when evaluated in accordance with Clause 5.2. 4.1.3 Quality of work Fixtures shall not have any exposed sharp or jagged edges, burrs, cracks, or other defects that might affect their use and serviceability (see Clause 5.2).
