7 METHODS OF TESTS FOR WATER CLOSETS7.1 Laboratory Tests for Waste Removal andWater Consumption
7.1.1 General. This Section presents test methodsand performance requirements for water closets withrespect to waste removal and water consumption.These test methods and performance requirementsshall apply to all water closets. Where materials otherthan vitreous china are used in a trapwaySection7.7,Closet Auger Test, of ASME A112.19.2M,shallbe conducted before conducting any hydraulic per-formance test.
7.1.2 Test Apparatus and General instructionsDuring all tests,pressure measuring methods and instruments shall conform to the intent of ASME PTC19.2.All flow measuring methods and instrumentsshall conform to the intent of ASME Interim Supplement 19.5,Part Il of Fluid Meters.The principal features of the test apparatus areshown in Figs.A-1，A-2A,and A-7 in Appendix AListed below are preparations and generalinstructionsfor testing.
7.1.21 Before connecting and testing fixtures.the water supply system shall be standardized in accordance with the procedures specified by Figs.A2A and A-2B with associated notes and proceduresand A.l of Appendix A.
7.1.2.2 The bowl shall be placed on a flat, levelsurface, the trap and outlet clear, and the bowl filledto trap weir level before making each test run.
7.1.2.3 Unit Adjustment. Test pressure for theindividual laboratory tests for tank-type and flushometer-type closets shall be set in accordance withTable 1.
(a) Gravity-Type Flush Tank Water Closets. Ateach supply pressure specified for the individual testsfor gravity-type flush tank water closets, the waterlevel in the tank and the fill time shall be adjustedaccording to the manufacturer’s instructions andspecifications for the tank. In the absence of suchinstructions and specifications, the tank shall be filledto the water line where marker or,in the absence ota mark, to a point l in.(25 mm) below top of highesipoint of the overflow, and the supply fill valve (ballcock) shall be set in the full flow position. Waterclosets which require special supply pressures shall beadjusted in accordance with manufacturer’s instructions. This requirement shall apply for all tests.
(b) Testing One-Piece Water Closets.Testing shallbe done in accordance with manufacturer’s instructions. In the absence of manufacturer’s instructions,the unit shall be tested at 20 psig static pressure.
(c) Flushometer Valve Water Closets. At each testpressure specified for individual tests for flushometer(pressurized flushing device) type water closets,thestop shall be adjusted to the manufacturer’s instructions and specifications.
