11、ial and performance specifications and use for protectors/insulators used onexposed waste and supplies of accessible fixtures installed in public/commercial and residential/private buildings. It is intended to serve as a guide for producers, distributors, architects, engineers,contractors, installer
12、s, inspectors, and users to promote understanding regarding the design,materials, applications, and installation of the product that conform to this Standard.With an aging population and the increase in the need for accessible fixtures in both the publicand private sectors, it is important that prod
13、ucts used in this environment meet minimumconsensus standard requirements. More and more occupancies are required to meet theICC/ANSI A117.1, Standard for Accessible and Usable Buildings and Facilities for Persons WithPhysical Disabilities, or ADA requirements. In addition, many persons are voluntar
14、ily demandingtheir occupancies be designed to be accessible as they age. Protectors/insulators covered underthis Standard are a critical part of ensuring that accessible fixtures are meeting these standardsand are adding an element of health and safety to their use. The minimum requirements containe
15、din this Standard will help ensure that these products meet the necessary performance and safetyrequirements and create a vehicle for independent testing and certification by third-party agencies.In addition, it will eliminate confusion in the marketplace and help with uniformity in codeenforcement.
16、 It was the reality of all these facts that created the need to develop theA112.18.9 Standard.This Standard was approved as an American National Standard by ANSI on August 25, 2011.ivASME A112 COMMITTEEStandardization of Plumbing Materials and Equipment(The following is the roster of the Committee a

22、lso cover products thatwill satisfy the requirements of ICC/ANSI A117.1,Standard for Accessible and Usable Buildings andFacilities for Persons With Physical Disabilities, and toestablish a generally acceptable performance standardfor protectors/insulators for exposed waste and sup-plies, so a physic
23、ally challenged person will be protectedwhen using a sink or lavatory in a public/commercialor private/residential facility.1.2 Units of MeasurementsValues are generally stated in U.S. Customary unitsand International System of Units (SI). U.S. Customaryunits shall be considered as the standard.2 DE
24、FINITIONSaccessible fixture: a plumbing fixture that complies withthe requirements of ICC/ANSI A117.1, Standard forAccessible and Usable Buildings and Facilities forPersons With Physical Disabilities.protectors/insulators: individual covers over waste andsupply pipes that isolate them to prevent inj
25、ury fromcontact with hot, cold, or sharp surfaces.supplies: the exposed water pipes to a fixture fitting con-sisting of stop valves and riser tubing under a sink orlavatory.voids: any unprotected area of exposed waste and sup-plies that could contact the user.waste: standard drains with tailpieces a
