This European Standard shall be given the status of a national standard, either by publication of an identical text or by e

21、ndorsement, at the latest by July 2009, and conflicting national standards shall be withdrawn at the latest by July 2009.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 subject of patent rights. CEN and/or CENELEC shall not be held responsible for identif

22、ying 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 and appliance categories given in this European Standard are in accordance with those

23、 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).

BS EN 419-1:2009EN 419-1:2009 (E) 5 1 Scope This European Standard specifies the requirements and test methods for the cons

26、truction, 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 as “appliances”. This European Standard is applicable to Type A1appliances only (see 4.3)

27、. 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 appropriate reference gas); d) appliances having fully pre-mixed gas and air burners in

28、 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 burner upstream of the combustion zone; e) appliances in which the supply of combustion air a

29、nd/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 be type tested would need to be subject to further consideration. Requiremen

30、ts 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.

40、e intended for installation at a height above head level, which is designed to heat the space beneath by radiation and in which the heat is produced by means of burning the fuel at or near the outer surface of a material such as a ceramic plaque or gauze, or by means of an atmospheric burner heating

41、 a gauze or similar material 3.1.2 atmospheric burner aerated burner in which the air for combustion is entrained at atmospheric pressure BS EN 419-1:2009EN 419-1:2009 (E) 7 3.1.3 inlet connection the part of the appliance intended to be connected to the gas supply 3.1.4 mechanical joint means of en

43、onveys or contains the gas between the appliance gas inlet connection and the burner(s) 3.1.6 restrictor device with an orifice, which is placed in the gas circuit so as to create a pressure drop and thus reduce the gas pressure at the burner to a predetermined value for a given supply pressure and

44、rate 3.1.7 gas rate adjuster component allowing an authorized person to set the gas rate of the burner to a predetermined value according to the supply conditions NOTE 1 Adjustment can be progressive (screw adjuster) or in discrete steps (by changing restrictors). NOTE 2 The adjusting screw of an ad

45、justable regulator is regarded as a gas rate adjuster. NOTE 3 The action of adjusting this device is called “adjusting the gas rate”. NOTE 4 A factory sealed gas rate adjuster is considered to be non-existent. 3.1.8 setting an adjuster immobilizing a gas rate adjuster by such means as e.g. a screw,

46、after the gas rate has been adjusted by the manufacturer or installer 3.1.9 sealing an adjuster term applied to any arrangement in respect of the adjuster such that any attempt to change the adjustment breaks the sealing device or sealing material and makes this interference apparent NOTE 1 A factor

47、y sealed adjuster is considered to be non-existent. NOTE 2 A regulator is considered to be non-existent if it has been factory sealed in a position such that it is not operational in the range of supply pressures corresponding to the appliance category.
