scope:

This Standard establishes physical, material, testing, and marking requirements for six-liter water closets that incorporate a water-conserving dual flushing feature into the design of the fixture. The tests specified in this Standard are for removal of liquid wastes and toilet tissue or other comparable waste loads that are expected when actuating the reduced flush feature of the unit. The use of alternate materials or methods is permitted, provided that the proposed material and method comply with the performance requirements and the intent of this Standard.
