ASME A112.19.14:2006 pdf download Six-Liter Water Closets Equipped With a Dual Flushing Device
(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.(d)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 shall
be 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 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. × 4.5 in-(114 mm x 114 mm). The single-ply toilet paper shallfirst meet both the absorption and wet tensile strengthrequirements given in paras.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. Schedule 40 Pvc pipe.The paper shall be slid off the pipe. The tube of papershall be grasped approximately halfway down its lengthand shall be turned inside out and down over itself.This shall result in a ball approximately 2 in.(51 mm)in diameter. The ball (straight edges down) shall bedropped into a pan of water. The time it takes for theball to become fully saturated and sink below the watersurface shall be recorded.
b) Performance Requirement.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. Schedule 40 PvC coupling andunion nut shall be used as a frame to hold the toilet
paper for the wet tensile strength test.Place one sheetof the toilet paper on the coupling and the union nutshall be slid over the coupling.The frame shall beinverted and the paper shall be submerged in water for5 sec.The frame shall then be removed from the waterand shall be returned to an upright position.A 0.312 in.(8 mm) diameter steel ball weighing 2 g ± 0.1 g shallbe placed in the center of the wet sheet.
)Performance Requirement. The sheet shall supportthe steel ball without any evidence of tearing.
3.2.4.2Test Method. The four 2 in. to 3 in.(51 mmto 76 mm) balls of paper that comply with paras.3.2.4.1.1and 3.2.4.1.2 shali be dropped into the water directlyabove the well and shall be allowed to wet out com-pletely. Within 5 sec after wetting occurs, the bowl shallbe flushed. This procedure shall be repeated until threesets of data are obtained. Note whether any paper isleft in the bowl. Flush again and collect any paper thatdischarges from the outlet.
3.2.4.3 Performance Requirement. No paper shallremain in the well after each initial flush.
3.2.5 Durability Test
3.2.5.1 Test Method. The water closet shall becycled 15,000 cycles in the full flush mode and, aftereach of the four full flushes, one reduced flush shall bemade followed by 60,000 cycles in the reduced volumeflush mode.
3.2.5.2 Performance Requirement.At the comple-tion of the test, the dual flush switch, actuator, or leversshall show no sign of deterioration that would affectperformance.They shall function smoothly and shallactivate with a force of 5 lbf(22 N) or less.”
MARKING
4.1 ldentification of Flush Mode Options
Identification of flush mode options shall be depictedon the actuator.This identification shall be either bygraphic display or lettering, or shall be intuitivelyapparent.
4.2 Water Closets
(a) The water closet shall be legibly marked as speci-fied in ASME A112.19.2 or ANSI Z124.4, as appropriate.(b)Water closets equipped with a dual flush deviceshall be marked with the reduced flush volume andthe designation ASME A112.19.14 to signify compliancewith this Standard. The location of this mark shall bedetermined by the manufacturer and is not required tobe permanent, but it shall be visible after installation.The label shall be intended for removal by the occupantonly, and this shall be so stated on the label.
