ASME A112.19.14 pdf download.Six-Liter Water Closets Equipped With a Dual Flushing Device.
ASME A112.19.14 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 of alternate 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 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):
ANSI Z124.4, Plastic Water Closet Bowls and Tanks
Publisher: International Association of Plumbing and Mechanical Officials (IAPMO), 5001 East Philadelphia Street, Ontario, CA 91761
ASME Al 12.19.2, Vitreous China Plumbing Fixtures and Hydraulic Requirements for Water Closets and Urinals

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—cousumptio,i wahr closl: 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 for each water closet type, and not exceeding 2 gal (7.6 L) at any one test pressure (based upon average values from thethree-run test).
3.2.4.2 Test Method. The four 2 in. to3 in. (51 mm to 76mm) balls of paper that comply with paras. 3.2.4.1.1 and 3.2.4.1.2 shall be dropped into the water directly above the well and shall be allowed to wet out completely. Within 5 sec after wetting occurs, the bowl shall be flushed. This procedure shall be repeated until three sets of data are obtained. Note whether any paper is left in the bowl. Flush again and collect any paper that discharges from the outlet.
3.2.4.3 Performance Requirement. No paper shall remain in the well after each initial flush.
3.2.5 Durability Test
3.2.5.1 Test Method. The water closet shall be cycled 15,000 cycles in the full flush mode and, after each of the four full flushes, one reduced flush shall be made followed by 60,000 cycles in the reduced volume flush mode.
3.2.5.2 Performance Requirement. At the completion of the test, the dual flush switch, actuator, or levers shall show no sign of deterioration that would affect performance. They shall function smoothly and shall activate with a force of 5 lbf (22 N) or less.
4 MARKING
4.1 Identification of Flush Mode Options
Identification of flush mode options shall be depicted on the actuator. This identification shall be either by graphic display or lettering, or shall be intuitively apparent.
4.2 Water Closets
(a) The water closet shall be legibly marked as spedfied in ASME Al 12.19.2 or ANSI Z124.4, as appropriate.
(6) Water closets equipped with a dual flush device shall be marked with the reduced flush volume and the designation ASME Al 12.19.14 to signify compliance with this Standard. The location of this mark shall be determined by the manufacturer and is not required to be permanent, but it shall be visible after installation. The label shall be intended for removal by the occupant onl and this shall be so stated on the label.
