25、diant heaters”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2006, and conflicting national standards shall be withdrawn at the latest by Decem
26、ber 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 mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relat
27、ionship with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. This part of EN 416 complements EN 416-1: “Single burner gas-fired overhead radiant-tube heaters - Part 1: Safety”. It is intended that this standard is reviewed 3 years after publication. Ac
28、cording to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lith

EN 416-2:2006 (E) 5 1 Scope This European Standard specifies the requirements and test methods for the rational use of energy of non-domestic gas fired overhea
30、d radiant tube heaters incorporating a single burner system under the control of an automatic burner control system, referred to in the body of the text as appliances. This standard is applicable to Type A2, A3, B12, B13, B22, B23, B42, B43, B52, B53, C12, C13, C32and C33appliances intended for use
31、in other than domestic dwellings, in which the supply of combustion air and/or the evacuation of the products of combustion is achieved by mechanical means located upstream of the draught diverter, if provided. This standard is not applicable to: a) appliances designed for use in a domestic dwelling
32、; b) outdoor appliances; c) appliances of heat input in excess of 120 kW (based on the net calorific value of the appropriate reference test 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 lev
33、el 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 the combustion zone. This standard is applicable to appliances which are intended to be type tested. Requirements for appliances which are not intended to be type tested n
