<br />i <br /> <br />8 <br /> <br />Table 1 (coat'd) <br /> <br />SANITARY PERFORMANCE TEST METHODS AND REQUIREMENTS <br />ANSI Al12.1P.6 (coat'd) <br /> <br />cylinders remaining In the well and those passing throUBh the trapway. Repeat the <br />procedure until five sets of dati are obtained. <br /> <br />Performance Rtqulmnmt: <br />A total of at least fifteen cylinders shall be flushed out In the five In1tlal flushes, and not <br />less than two cylinders shall be flushed out In the In1tlal flush of each test run. <br /> <br />Surface Washiq <br /> <br />4) Ink Test - felt tip pen with dark color water soluble Ink. <br /> <br />Procedurr:: <br />The flushing surface shall be scrubbed clean with commercial scouring powder. The <br />surface shall be rinsed and dl1ed With 011 free air. Draw a line around the drr;umference of <br />the flushing drde one-Inch below the rim lets. TrIp the flush release device. Measure the <br />lengths of the unwashed line segments and record their approldmate position. Repeat the <br />procedure until three sets of data are obtaIned. <br /> <br />Ptr(ormance Rlqulmnmt: <br />The total length of line sepents remaining on the flushIng surfate after each InitIal <br />flush shall not exceed two Inches and no Indlvldual segment shall be longer than one. <br />half Inch, based on the average of the three test runs. <br /> <br />Water ChlUlle <br /> <br />5) Dye Test - water soluble dye. polar brilliant blue RAWL. <br /> <br />Procedure: <br />a) Prepare a concentrated dye solution In the ratio of 30 grams pet liter. <br />b) Determine the volume of trap seal by measurement. <br />c) Prepare reference solutions In dilution ratios of 10, 20, SO, 100, 200, SOO and <br /> <br />ASPE Research Foundation <br />
