ASME A112.18.1:2003 pdf free download PLUMBING FIXTURE FIT TINGS
metering faucet: a faucet that, after actuation, dispenseswater for a predetermined volume or period of time.Fixed or adjustable cycle duration or volume areallowable.
mixing oaloe, single control: fitting with a single controlthat shall serve to turn water on and off, and to changevolume and temperature by means of a single handle.mixing oalDe,single-handle: fitting that,when suppliedwith both hot and cold water, changes the dischargewater temperature by means of a single handle.
mixing valve,single-handle, cycling type: single-handlemixing valve that rotates from off, through cold and mixto hot, and then in reverse to shut off.
mixing vaIve, two-handie: a combination fitting with sepa-rate hot and cold water control valves.
ronpoatable woater: contaminated water, not suitable forhuman or animal consumption,or water contained inany receptor.
permanent mark or label: a mark or a label that is intendedto remain in the applied position for the lifetime of thefitting under conditions of normal use.
pysical oapor deposition (PVD): a family of coating pro-cesses in which the surface layer is formed by the deposi-tion of individual atoms or molecules of a materiai thatis vaporized from a solid or liquid source, transportedthrough a low pressure gaseous or plasma environment,and condensed on a substrate surface.
pit: a small depression or cavity.
potable water: water that is satisfactory for drinking, culi-nary,and domestic purposes,and meets the require-ments of the health authority having jurisdiction.
pressure enoelope: outside part of the fitting that with-stands and contains the water pressure.
primary outlet: outlet from the fitting on the dischargeside of the control valve through which water will dis-charge unless diverted to another outlet.
public lavatory fittings: fixture fittings designed to beinstalled in nonresidential bathrooms that are open topublic access.
rigid waterway: any cross section of a waterway that iscapable of transnitting a damaging load to the body ofthe fitting.
seat disk: disk or washer that, when compressed againstthe seat, provides a watertight seal.
secondary outlet: the outlet from the fitting, other thanthe primary outlet on the discharge side of the valve,through which water may be discharged.
self-closing faucet: faucet that is designed to close itselfimmediately upon release of the handle.
shall: where used, indicates a mandatory requirement.significant surface: exposed surface that, if marred, woulddetract from the appearance of the fitting.
standard tools: tools,such as a screwdriver, key wrench,flat jawed wrench, and pliers, which are normally car-ried by plumbers for the installation and naintenanceof plumbing.
stop: valve for the purpose of controlling the flow ofwater.
supply stop: valve,either integral or separate,that isplaced ahead of a terminal fitting to shut off the supplyto that terminal fitting.
surface defect: any pit, blister, crack, pceling, or discolor-ation.
terninal fitting: last valve before atmospheric discharge.oalve: fitting by which the flow may be started,stopped,and regulated by a movable part that opens and/ orobstructs one or more passages.
GENERAL REQUIREMENTS2.1Toxicity Evaluation
All materials or products that come into contact withdrinking water shall conply with NSF 61.Supply fit-tings covered by the scope of NSF 61 shall comply withthe requirements of that standard.
Solder and fluxes containing lead in excess of 0.2%shall not be used in contact with potable water. Metalalloys in contact with potable water shall not exceed 8%lead content.
2.2 Coatings
2.2.1 Electrodeposited Coatings on Metals
(a)Appearance. The significant surfaces of the platedarticle shall be free of surface defects, roughness,anduncoated areas, and shall not be stained.
) Adhesion. The electrodeposited metallic coatedparts shall meet the performance requirements by con-formance to one of the following adhesion tests asdefined in ASTM B 571:
(1) burnishing test
(2) file test
(3) grind-saw test
(4) heat quench test
(c) Corrosion Test. Electrodeposited coatings shall be subjected to the corrosion test of ASTM B 456 for the applicable service condition as defined in para. 2.2.4. ASTM G 85, Test Method Annex A1, shall also be an acceptable method instead of ASTM B 287. After expo- sure, there shall not be more than one surface defect per 1 in.2 (645 mm2) of the significant surface area. Surface defects shall not be more than 0.03 in. (0.8 mum) in any dimension.
