11 Scope
This Standard establishes physical, aterial, testing.and marking requirements for six-jiler waler ciuseisthat incorporate a water-conserving dual flushing featureinto the design of the fxture. The tests specified inthis Standard are for removal of liquid wastes andtoilet tissue or other comparable waste loads that areexpected when actuating the reduced flush feature ofthe unit. The use of alternate materials or methods ispermitted provided that the proposed material andmethod comply with the performance requirements andthe intent of this Standard.
