This European Standard shall be given t

23、he status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2009, and conflicting national standards shall be withdrawn at the latest by July 2009. Attention is drawn to the possibility that some of the elements of this document may be the su

24、bject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 419-1:1999. In particular, it should be noted that this standard no longer includes requirements for Type B1appliances. The test gases, test pressures a

25、nd appliance categories given in this European Standard are in accordance with those specified in EN 437:2003. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive(s). For

26、relationship with EC Directive(s), see informative Annex ZA which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus

28、41 Scope This European Standard specifies the requirements and test methods for the construction, safety, classification and marking of non-domestic gas-fired overhead luminous radiant heaters for environmental comfort, incorporating an atmospheric burner system referred to in the body of the text a

29、s “appliances”. This European Standard is applicable to Type A1appliances only (see 4.3). This European Standard is not applicable to: a) appliances designed for use in domestic dwellings; b) outdoor appliances; c) appliances of heat input in excess of 120 kW (based on the net calorific value of the

30、 appropriate reference gas); d) appliances having fully pre-mixed gas and air burners in which: 1) either the gas and all the combustion air are brought together just before the level of the combustion zone; or 2) the pre-mixing of the gas and all combustion air is carried out in a part of the burne

31、r upstream of the combustion zone; e) appliances in which the supply of combustion air and/or the removal of the products of combustion is achieved by integral mechanical means. This standard is applicable to appliances which are intended to be type tested. Requirements for appliances which are not

32、intended to be type tested would need to be subject to further consideration. Requirements concerning the rational use of energy have not been included in this European Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
