Sensor automatic thermostatic faucets
1 Scope
This standard specifies the terms and definitions, classification and labeling, requirements, test methods, inspection rules as well as marking, packaging, transportation and storage of sensor automatic thermostatic faucets (hereinafter referred to as “faucet”).
This standard is applicable to the sensor automatic thermostatic faucets with nominal pressure not greater than 0.5MPa and hot water temperature not greater than 85℃, which are installed in sanitary fittings such as washroom (toilet, bathroom, etc.), kitchen, hospital, hotel, etc., controlled by sensor switch, opened and closed by electrically operated valve, and automatically controlled by preselected temperature for the outlet water temperature.
