This Act not onlyaddressed energy issues but also
13、included criteria for water conservation products in the UnitedStates that became effective in January 1994. As a complement to the enactment of this Act, theplumbing industry had already developed numerous water-efficient plumbing products thatimproved the performance of 1.6 gal per flush water clo
14、sets.One recent advance in the development of water closets is the use of dual flush technologythat allows the consumer to flush with either a short flush, 1.1 gal (4.1 L) or less, or a long orfull 1.6 gal (6 L) flush or less, depending upon need. This Standard addresses the performanceof these prod
15、ucts.This Standard establishes test criteria for 1.6 gal (6 L) dual flush water closets. It was preparedby an ad hoc committee from the International Association of Plumbing and Mechanical Officials(IAPMO). It was then referred to ASME and assigned to the A112 Project Team 19.14. It wassubsequently
16、reviewed and approved by the ASME A112 Standards Committee.The 2006 revision updated the reference to ASME A112.19.6 due to it being discontinued andits requirements included in ASME A112.19.2. Additionally, a typographical error in para. 3.2.5.1pertaining to the size of the toilet paper was correct
17、ed, para. 3.2.3.1(c) was revised to reduce theamount of water to which the dye solution has to be added to achieve a control sample of 17:1,and para. 3.2.3 (Rim Wash Test) was deleted. This test was deleted because it is more appropriatefor a full flush rather than a short flush.This revision update
18、s the designator for the two referenced standards, brings this Standard inline with the harmonized ASME A112.19.2/CSA B45.1 standard thatdoes not require the designa-tion of the standard on a label affixed to the product, and updates the test media to allow theuse of toilet paper with sheets of an e
19、quivalent surface area.Suggestions for the improvement of this Standard are welcome. They should be addressed toThe American Society of Mechanical Engineers, Secretary, A112 Standards Committee,Two Park Avenue, New York, NY 10016-5990.This Standard was approved as an American National Standard on De
