ASME A112.19.19-2016 pdf download.Vitreous China Nonwater Urinals.
finish: texture and condition of surface other than color. fire check: fine shallow crack in the body not covered with glaze (when covered with glaze so as to be easily cleaned, it is not detrimental). first quality: first-class ware in conformance with the grade limitations and other requirements of this Standard, shall also be permitted to be called grade “A” ware. fixture: the china piece only, without trim. flood level: the portion of a plumbing fixture that will spill over when the fixture drain is shut or constricted. glaze: the smooth, glass-like ceramic coating on a vitre- ous china surface that imparts impermeability and cov- ers the body. nonwater consuming urinal: a plumbing fixture that is designed to receive and convey only liquid waste through a trap seal into the gravity drainage system, without the use of water for such function. permanent markings: markings that are fired, cast, sand- blasted, etched, stamped, or otherwise not removable, except by excessive work or extraordinary means. pinhole: a small hole in the glazed surface up to and including 1 ⁄ 16 in. (2 mm) in maximum dimension. pit: a hole in the glazed surface larger than 1 ⁄ 16 in. (2 mm) in diameter. polishing mark: a spot not larger than 3 ⁄ 8 in. (10 mm) in maximum dimension where some minor blemish has been removed by polishing. pottery square: a square 2 in. (50 mm) on each side. For grading purposes, it shall be a 2-in. (50-mm) square hole cut in a small sheet of any flexible material, such as rubberor paper, forconvenience inslidingover irregular surfaces to determine segregation. rim: the unobstructed open edge of a fixture. roughing-in measurement: dimensions from finished wall or floor to center of waste or supply opening or mount- ing holes. sanitary: for the purposes of this Standard, indicates an aesthetic condition of cleanliness, not microbiologically clean. segregation: more than the allowable number of defects in a pottery square. speck: an area of contrasting color less than 1 ⁄ 32 in. (1 mm) in maximum dimension. Specks less than 1 ⁄ 100 in. (0.3 mm) in maximum dimension, unless in sufficient number to form a discoloration, are not counted. spot: an area of contrasting color 1 ⁄ 32 in. (1 mm) up to and including 1 ⁄ 8 in. (3 mm) in maximum dimension. 2 spot, large: an area of contrasting color greater than 1 ⁄ 8 in. (3 mm) in maximum dimension. trap: a fitting, device, or integral fixture portion so designed and constructed as to provide a liquid seal that will prevent the back-passage of sewer gas without materially affecting the flow of sewage or wastewater through it. trap dip: the highest point of the opening from the well into the trapway. trap-seal depth: the vertical depth of liquid between the highest part of the lower interior surface of a trap and the trap weir. trim: parts other than china regularly supplied with a fixture, e.g., wall hangers. Trim shall not include fittings (see ASME A112.19.5/CSA B45.15). urinal: a plumbing fixture that receives only liquid body wastes and conveys the waste through a trap seal into a gravity drainage system. urinal with drain-cleansing action: a nonwater urinal that automatically performs a drain-cleansing action after a predetermined amount of time or usage. Such a urinal can function and perform waste extraction without the drain-cleansing action. visible after installation: any surface that remains visible after the fixture has been installed, not necessarily from a normal standing position. visible surface: the surface that is readily visible to an observer in a normal standing position after installation of the fixture. vitreous china: as applied to plumbing fixtures (≤ 0.5% absorption) compounded of ceramic materials fired at high temperature to form a nonporous body with exposed surfaces coated with ceramic glaze fused to the body. warpage: a defect in a fixture resulting in a concave or convex gap between the fixture and the adjacent wall or floor. wavy finish: a defect in the finish having the appearance of numerous runs in the glaze, irregular or mottled. well: a pocket opened at the top, formed inside a urinal bowl at the entrance to the trap. 2 VITREOUS CHINA REQUIREMENTS 2.1 Absorption The average absorption of the ceramic test samples shall not exceed one-half of 1% (0.5%) when tested in accordance with ASME A112.19.2/CSA B45.1, para. 6.1. 2.2 Crazing No crazing shall be permitted when tested in accor- dance with ASME A112.19.2/CSA B45.1, para. 6.2.
