ASME A112.19.14:2013 pdf download Six-Liter Water Closets Equipped With a Dual Flushing Device
(30 mL) of the dye solution shall be added to the waterin the bowl and mixed thoroughly.
(c)0.34 oz (10 mL) of this solution shall be removedfrom the bowl and shall be added to 5.75 oz (170 mL)of clean water in a suitable container (i.e., dilution ratioof 17:1).A sample of this solution shall be set aside ina test tube or comparator vial as the control sample.rd)The water closet shall then be flushed severaltimes to ensure that all traces of the dye solution havebeen removed. One ounce (30 mL) of the dye solution[see para.3.2.3.1(a)] shall be added to the bowl. Theflushing device shall be actuated and released in a nor-mal manner and the test fixture shall be allowed tocomplete its filling cycle.A test tube or comparator vialshali be filled with water from the water closet bowland compared against the control sample. The test shallbe repeated two additional times and the results shallbe averaged.
NOTE: Use of a spectrophotometer shall be permitted in case ofdoubt; however, this method shall necessitate the use of a differentcolor dye.
3.2.3.2 Performance Requirement. A dilution ratioof at least 17:1 shall be obtained in each initial flush, forthe average of the three tests.
3.2.4 Toilet Paper Test
3.2.4.1 Test Media. The paper removal test in thereduced flush cycle shall be conducted as follows:(a) the test load shall be composed of four balls ofsix sheets of untreated single-ply toilet paper
b) each of the four balls in (a) shall be crumpled intoa 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. × 4.5 in.(114 mm × 114 mm) or of equivalent surface area. Thesingle-ply toilet paper shall first meet both the absorp-tion and wet tensile strength requirements given inparas.3.2.4.1.1 and 3.2.4.1.2,respectively.
3.2.4.1.1 Absorption
(a)Test Method.A six-sheet strip of the proposed toiletpaper shall be obtained. The paper shall be wrappedsnugly around a piece of 2-in.(51-mm) Schedule 40 Pvcpipe.The paper shall be slid off the pipe. The tube ofpaper shali be grasped approximately halfway down itslength and shall be turned inside out and down overitself. This shall result in a ball approximately 2 in.(51 mm) in diameter. The ball (straight edges down)shall be dropped into a pan of water. The time it takesfor the ball to become fully saturated and sink belowthe water surface shall be recorded.
(b)Performance Requiremenf. The paper ball shall sinkbelow the surface in’less than 3 sec.
3.2.4.1.2 Wet Tensile Strength (a) Test Method. A 2-in. (51-mm) Schedule 40 PVC coupling and union nut shall be used as a frame to hold the toilet paper for the wet tensile strength test. Place one sheet of the toilet paper on the coupling and the union nut shall be slid over the coupling. The frame shall be inverted and the paper shall be submerged in water for 5 sec. The frame shall then be removed from the water and shall be returned to an upright position. A 0.312-in. (8-mm) diameter steel ball weighing 2 g ± 0.1 g shall be placed in the center of the wet sheet. (b) Performance Requirement. The sheet shall support the steel ball without any evidence of tearing. 3.2.4.2 TestMethod. The four 2-in. to 3-in. (51-mm to 76-mm) balls ofpaperthatcomplywithparas.
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 com- pletely. 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 comple- tion 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 speci- fied in ASME A112.19.2/CSA B45.1 or CSA B45.5/ IAPMO Z124, as appropriate. (b) Water closets equipped with a dual flush device shall be marked with the reduced flush volume.
