ASME A112.19.14-2013 pdf download.Six-Liter Water Closets Equipped With a Dual Flushing Device.
1 GENERAL 1.1 Scope This Standard establishes physical, material, testing, and marking requirements for 6-L water closets that incorporate a water-conserving, dual-flushing feature into the fixture. The tests specified in this Standard are for the removal of liquid wastes and toilet tissue or other comparable waste loads that are expected when actuating the reduced flush feature of the unit. The use ofalternate materials or methods is permitted, provided that the proposed material and method com- ply with the performance requirements and the intent of this Standard. 1.2 Units of Measurement Values are stated 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 specified herein (the latest issue shall apply): ASME A112.19.2/CSA B45.1, Ceramic Plumbing Fixtures Publisher: The American Society of Mechanical Engineers (ASME), Two Park Avenue, New York, NY 10016-5990; Order Department: 22 Law Drive, P.O. Box 2900, Fairfield, NJ 07007-2900 (www.asme.org) CSA B45.5/IAPMO Z124, Plastic Plumbing Fixtures Publisher: International Association of Plumbing and Mechanical Officials (IAPMO), 5001 East Philadelphia Street, Ontario, CA 91761 (www.iapmo.org) 1.4 Definitions dual flush: a feature that allows the user to flush 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 flush volume) less than or equal to 1.6 gal (6 L) over the range of test pressures as specified in ASME A112.19.2/CSA B45.1 for each water closet type, and not exceeding 2 gal (7.6 L) 1 at any one test pressure (based upon average values from the three-run test). 2 REQUIREMENTS 2.1 Operation The dual flush mechanism shall function by actuation and release of the selector control, switch, or handle and shall complete its cycle without requiring further action or holding by the user. 2.2 Water Closets Water closets equipped with dual flush features shall conform to the requirements of ASME A112.19.2/ CSA B45.1 or CSA B45.5/IAPMO Z124. 3 TESTING 3.1 Full Flush Mode Water closets equipped with dual flush features shall meet all the requirements of ASME A112.19.2/ CSA B45.1 for low consumption water closets when the full flush 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 3.2.4 shall also meet the performance requirements of para. 7.3 of ASME A112.19.2/CSA B45.1. 3.2.2 Reduced Flush Volume Test. The reduced flush volume shall not exceed 1.1 gal (4.1 L) per flush when tested in accordance with para. 7.4 of ASME A112.19.2/ CSA B45.1. This testing shall be conducted before the durability testing in para. 3.2.5. The same testing shall be conducted after the durability testing in para. 3.2.5 and the reduced volume shall notvarymore than0.11 gal (0.41 L). 3.2.3 Dye Test 3.2.3.1 Test Method (a) 0.18 oz (5 g) of methylene blue powder shall be added to 0.26 gal (1 L) of water and mixed thoroughly in a clean container. (b) The water closet under test shall be flushed once and allowed to complete its filling cycle. One fluid ounce  (30 mL) of the dye solution shall be added to the 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 5.75 oz (170 mL) of clean water in a suitable container (i.e., dilution ratio of 17:1). A sample of this solution shall be set aside in a test tube or comparator vial as the control sample. (d) The water closet shall then be flushed several times to ensure that all traces of the dye solution have been removed. One ounce (30 mL) of the dye solution [see para. 3.2.3.1(a)] shall be added to the bowl. The flushing device shall be actuated and released in a nor- mal manner and the test fixture shall be allowed to complete its filling cycle. A test tube or comparator vial shall be filled with water from the water closet bowl and compared against the control sample. The test shall be repeated two additional times and the results shall be averaged. NOTE: Use of a spectrophotometer shall be permitted in case of doubt; however, this method shall necessitate the use of a different color dye. 3.2.3.2 Performance Requirement. A dilution ratio of at least 17:1 shall be obtained in each initial flush, for the average of the three tests. 3.2.4 Toilet Paper Test 3.2.4.1 Test Media. The paper removal test in the reduced flush cycle shall be conducted as follows: (a) the test load shall be composed of four balls of six sheets of untreated single-ply toilet paper (b) each of the four balls in (a) shall be crumpled into a loose ball measuring 2 in. to 3 in. (51 mm to 76 mm) in diameter. The standard size test sheet shall be 4.5 in. 5.4 .ni؋ (114 mm 411 ehT .aera ecafrus tnelaviuqe fo ro )mm؋ single-ply toilet paper shall first meet both the absorp- tion and wet tensile strength requirements given in paras. 3.2.4.1.1 and 3.2.4.1.2, respectively.
