ASME A112.19.14-2006 pdf – Six-Liter Water Closets Equipped With a Dual,Flushing Device.
Id) 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 Isee para. 323.1(a)I shall be added to the bowl. The flushing device shall be aduated and released in a normal 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. Thc test shall be npeated two additional times and the results shall be averaged.
MJTE: L) cit a pectmphokwnr5er shall be permitted in case 04 doubt; howevçr. ihr method shall or essitair the use ota diltcrrnt color dye. Performance Requirement. A dilution ratio oat least 17:1 shall be obtained in each initial flush, for the average of the three tests.
3.2.4 Toilet Paper Test Test Media. The paper removal test in the reduced flush cycle shall be conduded as follows:
(a) the test load shall be composed of four balls of Six 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 sire test sheet shall be 4.5 in. x 4.5 in. (114 mm X 114 mm). The single-ply toilet paper shall first meet both the absorption and wet tensile strength requirements given in paras. and respectively. Absorption
a Test Method. A six-sheet strip of the prope-ed toilet paper shall be obtained. The paper shall be wrapped snugly around a piece of 2 in. Schedule 40 PVC pipe. The paper shall be slid off the pipe. The tube of paper shall be grasped approximately halfway down its length and 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 be dropped into a pan of water. The time it takes for the ball to become fully saturated and sink below the water surface shall be recorded.
(b) Performance Requirement. The paper ball shall sink below the surface in less than 3 sec. Wet Tensile Strength
(a) Test Method. A 2 in. 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 (or 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 ± (LI 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. Test Method. The four 2 in. to 3 in. (51 mm to 76mm) balls of paper that comply with paras. 3.2A1.l and 314.1.2 shall be dropped into the water directly above the well and shall be allowed to vet out corn. 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, Performance Requirement. No paper shall remain in the well after each initial flush.
3.2.5 Durability Test Test Method. The water closet shall be cycled 15M00 cyclei in the full flush mode and, after each of the four full flushes, one rcduced flush shall he made followed by 60,000 cycles in the reduced volume flush mode. 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 lese.
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.
42 Water Closets
(a) The water closet shall be legibly marked as spedfied in ASME Al 12.19.2 or ANSI Z124,4, as appropriate.
(b) Water closets equipped with a dual flush device shall be marked with the reduced flush volume and the designation ASME A112,19,14 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 only, and this shall be stated on the label.
