IAPMO IGC 316-2015 Self-Cleaning Water Closets

1.1 Scope
This standard covers water closets with integral self-cleaning systems that operate by introducing liquid chemical cleaning agents into the water channels of the water closet during a specific cleaning cycle, separate from the normal flush cycle.
Note: The design of the self-cleaning system is intended to ensure that it does not interfere with the primary flushing function of the water closet.
