36、uction In respect of potential adverse effect on the quality of water intended for human consumption, caused by the product covered by this standard: a) This standard provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA. b) I
37、t should be noted that, whilst awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and or the characteristics of this product remain in force. DIN EN 1487:2014-09 EN 1487:2014 (E) 7 1 Scope This European Standard specifies dimensions, materials and
38、 performance requirements (including methods of test) for hydraulic safety groups, of nominal sizes from DN 15 to DN 25, having working pressures1)from 0,1 MPa (1 bar) to 0,7 MPa (7 bar). Hydraulic safety groups are intended for fitting to the potable water supply of storage water heaters, having a
39、maximum storage temperature of 95C. Hydraulic safety groups limit the pressure in hot water heaters, prevent the backflow of water into the main circuit and prevent the discharged water to get into contact with the water in the water heater. Hydraulic safety groups do not control the temperature. Th
40、ey ensure the hydraulic safety of water heaters if the mechanical resistance of the water heater remains at least equal to the rating pressure. NOTE The use of the device specified in this European Standard does not override the need to use controls (e.g. thermostats and cut-outs) which act directly
41、 on the power sources of water heaters. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
