China —
Non-vitreous china —ceramic material in which porosity results in a water absorption of between0.5 and 15.0% of the original weight of the dry specimen (see Clause 6.1).
Vitreous china — ceramic material fired at a high temperature to form a non-porous body with amaximum water absorption of 0.5% of the original weight of the dry specimen (see Clause 6.1).Critical level(CL)-— the highest water level of a supply fitting at which back siphonage will not occur.Defect —
Blister (large)- a hollow raised portion of the glazed surface of a fixture with a dimension greaterthan 3 mm (o.i3 in).
Bubble — a raised portion of the glazed surface of a fixture or a sand speck whose largest dimensionis less than 1 mm (o.04 in).
Crack – a fracture in the glaze or the body of a fixture, but not a dunt or a craze.craze (crazing)- fine cracks in the surface finish.
Discoloration — a coloured spot with a dimension greater than 6 mm (0.25 in) or specks or spots insufficient number that a change in colour is produced.
Dull or eggshell finish — a dead, flat, slightly matted, undeveloped glaze or semi-glazed finishwith numerous very fine pinholes.
Note: Dull or eggshell finish is not to be confused with a satin or matte finish used for decorative purposes.
Dunt— a hairline fracture extending through the body of a fixture and caused by strains duringmanufacturing.
Exposed body — an unglazed portion of a fixture with a dimension of 2 mm (0.08 in) or greater.
Fire check — a fine shallow crack in the body of a fixture that is not covered with glaze.
Pinhole — a hole in the glazed surface of a fixture whose largest dimension is 2 mm (0.08 in) or less.Pit— a hole in the glazed surface of a fixture with a dimension greater than 2 mm (0.08 in).
Speck — an area of contrasting colour whose largest dimension is between 0.3 and 1 mm (0.01 and0.04 in).
Spot — an area of contrasting colour whose largest dimension is greater than 1 mm (0.04 in) but lessthan 3 mm (0.13 in).
warpage — a defect in a fixture resulting in a concave or convex gap between the fixture and theadjacent wall or floor.
wavy finish – a defect in a finish that results in numerous irregular or mottled runs in the glaze.Fill time — the time from the instant the flush valve of a flush tank closes until the instant the fill valve iscompletely shut off.
Finish – the texture and condition of a surface (excluding colour).Fitting — a device that controls and guides the flow of water.
Fixture — a device that receives water, waste matter, or both and directs these substances into a drainagesystem.
Flood level- the level at which water will overflow a fixture.
Flush cycle — the complete operating sequence of a water closet or urinal in emptying its contents,cleaning its inside surfaces, and refilling the water seal.
Flushing device — a device for delivering water into a water closet bowl or urinal.
Flush valve — a valve for discharging water from a flush tank into a water closet bowl or urinal.Pressurized flushing device— a flushing device that is employed in non-gravity flushing systemsand uses the water supply to create a pressurized discharge to flush fixtures.
Note: Flushometer tanks, flushometer valves, and electronically controlled pressurized devices are examples ofpressurized flushing devices (see CSA B125.3 and ASSE 1037).
Flushometer tank – a flushing device that effectively enlarges the water supply pipe
immediately before the water closet bowl or urinal by being integrated within an accumulatorvessel affixed and adjacent to the fixture inlet.
Flushometer valve — a flushing device attached to a pressurized water supply pipe that, whenactuated, opens the pipe for direct flow into the fixture at a rate and in a quantity that enablesproper operation of the fixture. The valve then gradually closes to provide trap reseal in thefixture and avoid water hammer.
Note: The pipe to which the flushometer valve is connected should be large enough to enable delvery of waterat a sufficient rate for proper operation.
Flushing surface — a surface that is visible after installation and is wetted during operation of a watercloset or urinal.
Glaze – a smooth, impermeable, glass-like ceramic coating.
Gravity flush tank water closet — a water closet designed to flush the bowl with water supplied bygravity only.
lntegral – a cast or formed part of a fixture, e.g., a trap, seat, or flush tank.Lavatory – a washbowl or basin.
