24、19-2:2006 (E) 4Foreword This European Standard (EN 419-2:2006) has been prepared by Technical Committee CEN/TC 180 “Non-domestic gas-fired overhead radiant heaters”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publicatio
25、n of an identical text or by endorsement, at the latest by December 2006, and conflicting national standards shall be withdrawn at the latest by December 2006. This European Standard supersedes ENV 1259-1:1994, ENV 1259-2:1996 and ENV 1259-3:1996 This European Standard has been prepared under a mand
26、ate given to CEN by the European Commission and the European Free Trade Association and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. This part of EN 419 complements EN 419-1:
27、“Non-domestic gas-fired overhead luminous radiant heaters - Part 1: Safety”. It is intended that this standard would be reviewed 3 years after publication. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this E
28、uropean Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. E
29、N 419-2:2006 (E) 51 Scope This European Standard specifies the requirements and test methods for the rational use of energy 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 as “applia
30、nces”. 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 appropri
31、ate 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) pre-mixing of the gas and all combustion air is carried out in a part of the burner upstream of
32、 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 intended to b
33、e type tested would need to be subject to further consideration. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenc
34、ed document (including any amendments) applies.
