The Articles 6.1.1, 6.1.2, 6.4.1, 6.4.2, 6.4.3, 6.4.4, 6.4.5 and 6.4.6 of this Standard are
compulsory provisions; the rest are recommended.
The development of this Standard has adopted, through modifications, the American Society of
Sanitary Engineering ASSE 1016-2005 “Performance Requirements for Automatic
Compensating Valves for Individual Showers and Tub/ Shower Combinations”, and made
references to the European standards EN 1111.1998 “Thermostatic mixing valves (PN 10) -
General technical specification”, EN 1287.1999 “Low pressure thermostatic mixing valves --
General technical specifications”, ASME A112.18.1-2005/CSA B1125.1-2005 “Plumbing supply
fittings” and other foreign advanced standards. The main technical contents include.
-- All the materials applied by the products in direct touch with drinking water shall comply
with provisions of GB/T 17219;
-- Outlet water temperature stability. the deviation between the outlet water temperature of
mixing water and the set temperature shall be ≤ 2ºC;
-- Safety. Within the first 5s after cold water is stopped, the water yield shall be ≤200mL,
which shall be able to control the maximum outlet water temperature to be 49ºC;
-- After the service-life test of thermostatic faucet, the sealing performance and outlet water
temperature shall be within the changing range as specified.
The Annexes A, C, D, E, F, G and H are normative, while Annex B is informative.
This Standard was proposed by China Light Industry Federation.
This Standard shall be under the jurisdiction by the Subcommittee on Building Hardware of
National Technical Committee on Hardware of Standardization Administration of China.

Thermostatic Faucets
1    Scope 
This Standard specifies the terms and definitions, classification and marking, requirements, test
methods, inspection rules and marking, packaging, transportation and storage of thermostatic
faucets.
This Standard shall be applicable to the cold-hot water mixing faucets of which the nominal
pressure is not more than 0.5MPa; used under the condition that the hot water temperature is
not more than 85ºC; installed in a lavatory (water closet and bathroom, etc.), kitchen and other
sanitary facilities where the outlet water temperature is automatically controlled by the preset
temperature.
