China releases association standards for smart toilets 
On May 20, the Chaozhou Building Sanitary Ceramics Industry Association released association standards for smart toilets called “Smart Water Closets” (T/CBCSIA 1-2022), which will come into effect on Aug. 1. The standards cover performance grades, technical requirements, test methods, labeling and packaging of smart toilets (smart water closets) used in households and similar places.
Thirteen performance indicators, such as water consumption, flushing capability and energy consumption, are defined in the standards. Smart toilets are classified into three grades for each indicator so that each aspect of their performance can be understood clearly.
