ASME A112.19.3-2008 pdf download.Stainless steel plumbing fixtures.
0 Introduction 0.1 This harmonized Standard was developed in response to an industry request for a Standard for evaluation of plumbing fixtures that would be acceptable for use in both Canada and the United States. Harmonized Standards for plumbing fixtures made of other materials are also available or under development. 0.2 The concept of harmonization for plumbing fixtures arose in the early 1 990s, when a free trade agreement between Canada, Mexico, and the United States began to be discussed. Standards development organizations (SDOs) were at the forefront of these discussions and an opportunity soon arose for those SDOs involved in developing requirements for plumbing products to establish a process for harmonization. However, the effort to develop a trinational Standard stalled until 2001 , when ASME and CSA decided to develop a binational Standard for plumbing fittings. 0.3 Harmonization activities for plumbing fixtures standards were undertaken in 2004 by a Joint Harmonization Task Group (JHTG) on Plumbing Fixtures, in which the ASME and CSA plumbing fixtures committees were equally represented. The responsibility for procedural matters and final approval of technical content was assumed by technical committees at higher levels within each SDO. 1 Scope 1.1 This Standard covers plumbing fixtures made of stainless steel alloys and specifies requirements for materials, construction, performance, testing, and markings. Note: The term “corrosion-resisting steel” is also applied to stainless steel. 1.2 This Standard covers the following plumbing fixtures: (a) bathtubs; (b) bidets; (c) drinking fountains and water coolers; (d) lavatories; (e) shower bases; (f) urinals; and (g) sinks: (i) kitchen and bar sinks; (ii) laboratory sinks; (iii) laundry sinks; (iv) service sinks; and (v) utility sinks. 2 August 2008 © American Society of Mechanical Engineers ASME A112.19.3-2008/CSA B45.4-08 © Canadian Standards Association 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.

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. Horizontal surface — a surface forming an angle with the horizontal of less than 45°. Integral rim — a mounting rim that is an integrally formed part of a sink flange and has clamp-down devices for attaching the sink to the countertop. Lavatory — a washbowl or basin. Ledge — the flat area of a sink or lavatory on which supply fittings are normally mounted. Ledge-back sink — a single- or double-compartment sink with a ledge along the back that has openings for mounting supply fittings. 4 August 2008 © American Society of Mechanical Engineers ASME A112.19.3-2008/CSA B45.4-08 © Canadian Standards Association Mirror finish — a highly reflective finish with no visible polishing lines. Rim — the unobstructed open edge of a fixture. Satin finish — a surface with a soft sheen consisting of fine, regular polish lines in a uniform pattern. Urinal — a fixture that receives only liquid body waste and conveys the waste through a trap into a drainage system. Vertical surface — a surface forming an angle with the horizontal of 45 to 90°. Water closet — a fixture with a water-containing receptor that receives liquid and solid body waste and on actuation conveys the waste through an exposed integral trap into a drainage system.
