1 SCOPE AND PURPOSE ASME/ANSI A112.19.5-1979, Trim for Water 1.1 PurDose The purpose of this Standard is to establish a na- tionally recognized standard for plumbing fixtures of non-vitreous ceramic, including fixtures containing components of other recognized materials, for the guidance of manufacturers, distributors, and pur- chasers to promote better understanding between suppliers and users; and to furnish a basis for fair competition in furnishing such plumbing fixtures to meet the principal demands of the trade. 1.2 Scope This Standard covers physical requirements and test methods pertaining to material, grading, dimen- sions, certain features of construction, and types and sizes of plumbing fixtures of non-vitreous ceramic currently in general use and demand. Also given are definitions, inspection methods, and tests which es- tablish generally acceptable quality standards. Fix- tures included in this Standard are water closet tanks, lavatories, urinals without integral trap, bidets, bathtubs, shower receptors, kitchen and bar sinks, service sinks, and drinking fountains. The values stated in U.S. Customary units are to be regarded as the standard. 2 REFERENCED STANDARDS The following standards are referenced in this doc- ument. When the revisions to these standards are prepared, the updated edition shall apply. Closet Bowls, Tanks, and Urinals ASME/ANSI A112.19.6M-1990, Hydraulic Per- formance for Water Closets and Urinals ANSI A117.1-1986, Standard Specification for Making Buildings and Facilities Accessible and Us- able by Physically Handicapped People ANSI/ARI 1010-1984, Drinking Fountains and Self-contained, Mechanically Refrigerated Drinking Water Coolers ANSUASSE 1001-1982, Pipe Applied Vacuum Breakers ANSI/ASSE 1002-1986, Water Closet Flush Tank Fill Valves (Ballcocks) ASSE 1037-1986, Performance Standard for Pres- surized Plumbing Fixture Flushing Devices (Flush- ometers) IAMPO PS4-83, Shower Drains 3 NOMENCLATURE AND DEFINITIONS Nomenclature and definitions applicable to non- vitreous ceramic plumbing fixtures are as follows: bidet – a personal hygiene fixture with hot and cold water supply intended for genital and perineal clean- liness blister – a raised portion of the surface not greater than in. (3 mm) in maximum dimension blister (lave) – a raised portion of the surface greater than 1/8 in. (3 mm) in maximum dimension ASME/ANSI A112.1,2-1979, ~i~ G~~~ in plumb- bubble – a raised portion of the surface or a sand speck smaller than in. (1 mm) in maximum di- mension ing Systems ASME/ANSI A112.6.1-1988, Supports for Off-the- craze – fine cracks in the glaze Floor Plumbing Fixtures for Public Use discoloration – a colored spot over in. (6 mm) in ASME/ANSI A112.18.1M-1989, Plumbing Fixture maximum dimension or a sufficient number of specks Fittings or spots to give the effect of a change in color dull or eggshell finish – dead or flat finish, undevel- oped glaze, or a semi-glazed finish with numerous very fine pinholes, or slightly matted in appearance, not glossy; not to be confused with a satin or matte finish used for decorative purposes dunt – a hairline fracture extending through the body and caused by strains set up in the process of manufacture eartlzenware – one type of non-vitreous ceramic (see para. 4.1.1) , exposed body – unglazed portion in. (2 mm) or more in maximum dimension finish – texture and condition of surface other than color fire check – fine shallow crack in the body not cov- ered with glaze (when sufficiently covered with glaze so as to be easily cleaned, it is not detrimental) fireclay non-vitreous ceramic materials which in- clude in its composition, pre-fired clays (called grog) which are ground into small grains and are added to the slip. (See para. 4.1.1 for further delineation of fireclays.) first quality – first class ware in conformance with the grade limitations and other requirements of this Standard. May also be called “A” grade ware. fittings – adjuncts to a fixture subject to selection or options of the purchaser as, for example, faucets and waste plugs fivture – the ware only, without trim and/or fittings flush tank – a container for a measured quantity of water, fitted with an inlet valve (ballcock) and a flush valve, either wall hung or close coupled (with closet bowl), used to flush a water closet bowl by gravity force flush valve – a special form of valve located at the bottom of a flush tank used in flushing a water closet or urinal flushing surface – the surface, visible after installa- tion, which may be wetted during the operation of the fixture flushometer tank – a valve whose function is defined in jlushometer valve below, but integrated within an accumulator vessel affixed and adjacent to the fixture inlet so as to cause an effective enlargement of the supply line immediately before the flushometer valve jlushometer valve – a valve attached to a pressurized water supply pipe and so designed that when ac- tuated, it opens the line for direct flow into the fix- ture at a rate and quantity to properly operate the fixture, and then gradually closes to provide trap re- NON-VITREOUS CERAMIC PLUMBING FIXTURES seal in the fixture in order to avoid water hammer. The pipe to which this device is connected is, in itself, of sufficient size, that when open, will allow the de- vice to deliver water at a sufficient rate of flow for flushing purposes. integrul – a part cast integrally with the fixture such as a bubbler, trap, or seat non-vitreous ceramic – for the purpose of this Stan- dard, compound ceramic materials fired at high tem- perature, coated with ceramic glaze fused to the body, which does not peel or craze. Non-vitreous ce- ramic materials are classified as semi-vitreous, fire- clay, or earthenware based on grain size and percentage of absorption (see paras. 4.1.1 and 7.1). permanent – for the purpose of marking in this Stan- dard, permanent shall be fired, cast, sandblasted, em- bossed, stamped, etched, or otherwise not removable except by excessive work or extraordinary means (see Section 8) pinhole – a small hole in the glazed surface up to and including V16 in. (2 mm) in maximum dimension pit – a hole in the glazed surface larger than in. (2 mm) in diameter polkhing mark – a spot not larger than ’/* in. (10 mm) in maximum dimension where some minor blemish has been removed by polishing pottev square – a square 2 in. (50 mm) on each side. For grading purposes, it may be a 2 in. (50 mm) square hole cut in a small sheet of any flexible rna- terial, such as rubber or paper, for convenience in sliding over irregular surfaces to determine segrega- tion pressurized flushing devices – a product which uses the water supply to create a pressurized discharge to flush the fixture exclusive of gravity type flushing sys- tems. Flushometer valves and flushometer tanks are examples of pressurized flushing devices. This term may be called a pressurized flushing device in this Standard (see ASSE 1037).
