13、ment of anumber of special plumbing products to assist the physically challenged and the elderly in usingplumbing systems with greater ease and comfort. This Standard addresses bathtubs and whirlpoolbathtubs equipped with pressure sealed doors that will enable easier use by the consumer.These produc
14、ts have factory installed doors with the bathtub apron, thus allowing the batherto enter the fixture at approximately the same level as the floor. The door can be opened, allowingthe bather easier access to the bathtub. Once inside the fixture, the door is closed and the wateris turned on. Sensor sw
15、itches note the presence of water entering the vessel, thereby activatingan air pump that pressurizes the door seal and keeps the water within the bathing vessel. Uponcompletion of the bathing activity, the door can be opened only when the bath water is drainedfrom the vessel.This Standard establish
16、es test criteria for these fixtures to ensure that the bathtubs are watertightand sturdy. It was based on a standard of an ad hoc Committee of the International Associationof Plumbing and Mechanical Officials (IAPMO). The IAPMO standard was then referred to ASMEand assigned to the ASME A112 Project
17、Team 19.15. It was then reviewed and approved by theASME A112 Main Committee, and subsequently approved as an American National Standardon April 6, 2001.This is a revision of the performance requirements of primary and secondary seals.Suggestions for improvement of this Standard are welcome. They sh
18、ould be sent to the Secretary,ASME A112 Standards Committee, Three Park Avenue, New York, NY 10016-5990.This revision was approved as an American National Standard on March 5, 2012.ivASME A112 COMMITTEEStandardization of Plumbing Materials and Equipment(The following is the roster of the Committee a

25、RLPOOL BATHTUBS WITHPRESSURE SEALED DOORS1 GENERAL1.1 ScopeThis Standard establishes material, mechanical, elec-trical, marking, and testing requirements for bathtubs/whirlpool bathtubs with doors that are made water tightby the use of a pressure seal. It addresses the functionalperformance and phys
26、ical characteristics for a pressuresealed door of a bathtub/whirlpool bathtub. The dooris intended to allow for entry into the fixture when thetub is empty and to maintain water tightness when thetub is full. The use of alternate materials or methods ispermitted, provided the proposed material and m
27、ethodcomply with the performance requirements and intentof this Standard.(12) 1.2 Units of MeasurementThe values stated in either SI (metric) or inch/poundunits are to be regarded as the standard. In this Standard,the inch/pound units are shown in parentheses. Thevalues stated in each measurement sy
28、stem are equiva-lent in application; however, each system is to be usedindependently. Combining values from the two mea-surement systems can result in non-conformance withthis Standard. All references to gallon are in U.S. gallon.(12) 1.3 Reference StandardsThe following documents form a part of thi
