China - Proposed Water Efficiency Standard for Water Closets

​New water efficiency standard was proposed by China SAMR /State Administration for Market Regulation (Standardization Administration of the P.R.C.), reagarding water closets. 

This standard specifies the water efficiency limit value and grades, technical requirements, test methods and test devices for the water closets.
This standard applies to the water efficiency evaluation of water closets installed on cold water pipelines in building facilities, with water supply pressure not exceeding 0.6 MPa, using water as the main flushing medium and with water sealing function. ​
