22、an Standard provides no information as to whether the product may be used without restric-tion in any of the Member States of the EU or EFTA; b) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regu-lations concerning the use and/or the characte
23、ristics of this product remain in force. BS EN 15092:2008EN 15092:2008 (E) 5 1 Scope This European Standard specifies dimensions, materials and performance requirements (including methods of test) for in line hot water supply tempering valves for sanitary hot water systems, of nominal sizes from DN
24、15 to DN 50. Tempering valves reduce the temperature of sanitary hot water for distribution throughout the hot water system. The conditions of use are specified in Table 1. The valves are intended to be used with storage water heaters to provide tempered hot water to the terminal fitting. They are n
25、ot intended to control the temperature at the point of use. Tempering valves control the distribution temperature from a water heater to a preset value or an adjustable range, both between 45 C and 65 C.
