3、mentation of EN 15092:2008. The UK committee would like to draw attention to the following concerns: 1.Subclause 7.6.2 requires that flow changes be accomplished within 10,5 seconds. This necessitates that valve 5 shown in Annex B is more than a simple on/off control. 2.The acoustic test in Subclaus
4、e 8.2 references EN ISO 3822. This requires the test to be conducted with cold water at both inlets; therefore arrangements need to be made to enable adjustment of the temperature setting of the valve over the whole range in order to satisfy the requirements of EN ISO 3822 and Subclause 8.2. 3.Annex
5、es A and B are informative, yet there are several references to these Annexes within Clause 7. This could result in irreproducibility, and inconsistencies in certifications.

26、uirements (including methods of test) for in line hot water supply tempering valves for sanitary hot water systems, of nominal sizes from DN 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 specifie
27、d 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 not 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 a
28、djustable range, both between 45 C and 65 C.
