FOREWORDIn 1992,the Federal Energy Policy Act was enacted into law by Congress.This Act not onlyaddressed energy issues but also 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 closets.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,depending upon need.This Standard addresses the performance of theseproducts.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 reviewed and approved by the ASME A112 Standards Committee.This revision updates the reference to ASME A112.19.6 due to it being discontinued and itsrequirements included in ASME A112.19.2.Additionally,a typographical error in para.3.2.5.1pertaining to the size of the toilet paper was corrected,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 17:1and 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.Suggestions for the improvement of this Standard are welcome.They should be addressed toThe American Society of Mechanical Engineers,Secretary,A112 Standards Committee,ThreePark Avenue,New York,NY 10016-5990.This Standard was approved as an American National Standard on May 19,2006.No roproduction or notworking permitted without liconse from IHSNot for Resale
