13、. vi1 General. 12 General Requirements . 13 Testing . 24 Marking and Instructions 3iiiFOREWORDIn 1990, the Americans With Disabilities Act passed in Congress. This Act was intended toincrease the accessibility of building elements to those who have limitations in physical ability.As a result of the
14、technological response to the need for greater adaptability of plumbing compo-nents for accessibility purposes, this Standard and others are being prepared by ASMEStandards Committee A112, Standardization of Plumbing Materials and Equipment.This Standard relates to performance requirements for wall
15、mounted, pedestal mounted, adjust-able, elevating, tilting, and pivoting lavatory, sink, and shampoo bowl carrier systems and drainwaste systems. Such systems allow the user to adjust the location of a lavatory, shampoo bowl,or sink upwards and downwards. Some products also adjust from side to side
16、and/or front toback in order to maximize the ease of use of the fixture. Some products also pivot or tilt to allowgreater ease of fixture use. The performance tests within this Standard were determined to becommensurate with normal fixture use.The original Standard and the current revisions were bas
17、ed on standards that were developedby two ad hoc committees of the International Association of Plumbing and Mechanical Officials(IAPMO). The proposed standards were subsequently referred to the ASME A112 StandardsCommittee for development of an American National Standard.This revision provides new
18、and improved requirements, and test methods for elevating carriersystems, telescoping standpipe waste systems, elevating sinks, lavatories, and shampoo bowlsfor use by or with handicapped persons.Suggestions for improvement of this Standard are welcome. They should be sent to TheAmerican Society of
19、Mechanical Engineers; Attn: Secretary, A112 Standards Committee;Two Park Avenue; New York, NY 10016-5990.This Standard was approved as an American National Standard on December 9, 2014.ivASME A112 COMMITTEEStandardization of Plumbing Materials and Equipment(The following is the roster of the Committ
