(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.] 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. Performance Requirement. A dilutionratio 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 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. 4.5 in. (114 mm 114 mm) or of equivalent surface area. The single-ply toilet paper shall first meet both the absorp- tion and wet tensile strength requirements given in paras. and, respectively. Absorption
(a) Test Method. A six-sheet strip ofthe proposed toilet paper shall be obtained. The paper shall be wrapped snugly around a piece of 2-in.(51-mm) 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.
