This Standard eslablishes plhysical, material, lesting, and marking requirements for six-liter waier clusels that incorporate a water-conserving dual flushing feature into the design of the fixture. The tests specified in this Standard are for removal of liquid wastes and toilet tisslne or other comparable waste loads that are expected when actuating the reduced flush feature of the unit. The use of aternate materials or methods is permitted, provided that the proposed material and method comply with the performance requirements and the intent of this Standard. 1.2 Units of Measurement Values arc staltd in U.S. Customary units and the International System of Units (SI). The U.S. Customary units shall be considered as the standard. 1.3 Reference Standards The following documents form a part of this Standard to the extent specifed herein (the latest issue shall apply): ANSI Z124.4, Plastic Water Closet Bowls and Tanks Publisher: Internaional Association of Plumbing and Mechanical Officials (IAPMO). 20001 East Walnut Drive, South Walnul, CA 91789-2825 ASME A112 19 2M, Vitreous China Plumbing Fixtnres ASME A112. 19.6, Hydraulic Requirements for w ater Closets and Urinals Publisher: The American Society of Mechanical Engi- neers (ASME), Three Park Avenue, New Yorik, NY 10016-5990; Order Departument, 22 Law Drive, Fair- field, NJ 07007-2900. 1.4 Definitions dua!, flush: a feature that allows the user to fush the water closet with either a reduced or full volume of water, depending upon bowl contents.low. consumption water closet: a water closet having an average water consumption (total fush volume) less than or cqual to 1.6 gal (6 L) over the range of test pressures as specifed in ASME A112.19.6 for each water closet type, and not exceeding 2.0 gal (7.6 L) al any one lest pressure (based upon average values from the three run lest). 2 REQUIREMENTS 2.1 Operation The dual fush. mechanism shall function by actuation and release of the sclector control, switch, or handle and shall complete its cycle without lequiring further action or holding by the user. 2.2 Water Closets Water closets equipped with dua! fush features shall conform to the requirements of ASME A112.19.2M or ANSI Z124.4. 3 TESTING 3.1 Full Flush Mode Water closets equipped with dual fAush features shall meet all the requirements of ASME A112. 19.6 for low- consumption water closets when the full fush volume is activated. 3.2 Reduced Flush Mode 3.2.1 Trap Seal Restoration Test. The water closet as tested in paras. 3.2.2 through 3.2.5 shall also meet the performance requirements of para. 7.1.6.3 of ASME A112.19.6. 3.2.2 Reduced Flush Volume Test. The reduced ftlush volume shall not exceed 1.10 gal (4.1 L) per flush when tested in accordance with para. 7.1.6 of ASME A112.19.6. This testing shall be conducted before the durability testing in para. 3.2.6. The same testing shall be conducted after the durbility testing in para. 3.2.6 and the reduced volume shall not vary more than 0.11 gal (0.41 L). 3.2.3 Rim Wash Test. The water closet shall usc the test methods and meet the performance requirements of para. 7.1.4 of ASME A112.19.6, when in the rcduccd flush cycle. 3.2.4 Dye Test : 3.2.4.1 Test Method (a) 0.18 0Z (5 g) of methlylene blue powder shall be added to 0.26 gal (1 L) of water and mixed thoronghly in a clean container. (b) The water closet under test shall be fushed once and allowed to complete its flling cycle. One fuid ounce (30 mL) of the dye solution shall be added to he water in the bowl and mixed thoroughly. (C) 0.34 oz (10 mL) of this solution shall be removed from the bowl and shall be added to 16.9 0z (500 mL) of clean water in a suitable container (ie, dilution ration of 50:1). A sample of this solution shall be set asidc in a test tubc or comparator vial as the control samplc. (d) The water closet shall then be fushed several times to ensure that all uraces of the dye solution have beeu lemoved. One 1 oz (30 mL) of the dye solution [sce para. 3.2.4.1(a)] shall be added to the bowl. The fushing device shadl be actuated and reieased in a normal manner and the lest fixture shall be allowed to complete its filling cycle. A test tube or comparator vial shall be filled with water from the water closet bowi and compared against the controi sarmpie. The test shall be repeated lwo additional times and the resuits shall be averaged. NOTE: Use of a spectrophotometer shall be prmitted in case of doubt; however, this method shall necessitate the use of a different color dyc. 3.2.4.2 Performance Requirement. A dilution ratio of at least 50:1 shal! be obtained in each initial fush, for the average of the three tests. The procedure shall be repeated until three sets of data are obtained. 3.2.5 Toilet Paper Test 3.2.5.1 Test Media. The paper removal tcst in the rcduced fush cycle shall be conducted as follows: the test load shall be composed of four balls of six shcets of untreated singlc-ply toilet paper, each crumpled into a loose ball measuring 2 in. to 3 in. (51 mm to 76 mm) in diameter. The standaid size test sheet shall be42in.x42in.(114mmx114mm).ASME A112.19.14 pdf download.
