This European Standard sha

27、ll be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2010, and conflicting national standards shall be withdrawn at the latest by May 2010. Attention is drawn to the possibility that some of the elements of this document ma

28、y be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1020:1997. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, a

29、nd supports essential requirements of EC Directive(s). For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this document. This revision modifies EN 1020:1997. It has been prepared to incorporate requirements for combustion products evacuation ducts,

30、POCEDs, supplied as an integral part of the system to support the EU Directive 89/106/EEC on construction products under mandate M105. To this end it extends the scope of the standard to cover type B4and type B5 appliances. Furthermore, the opportunity presented by this revision has been taken to up

31、date the standard in respect to EN 437:2003. NOTE For countries requesting special categories (specified in EN 437:2003), the absence of specific information concerning A.3.3 and A.3.4 implies that the general requirements described in the body of the standard (see 4.1.1, 4.2.2, 4.2.3 and 4.2.5) als

32、o apply to these special categories. 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, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greec

33、e, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. BS EN 1020:2009EN 1020:2009 (E) 5 1 Scope This European Standard specifies the requirements and test metho

34、ds for the safety and efficiency of non-domestic gas-fired air heaters having a fan to assist the transportation of combustion air and/or flue gases, hereafter referred to as “appliances“. This includes appliances having forced draught burners. This European Standard applies to Type B12, B13, B14, B

35、22, B23, B42, B43, B44, B52, B53, C12, C13, C32, C33, C62and C63appliances with a heat input not exceeding 300 kW (based on net calorific value) intended for use in other than single unit residential dwellings. It also applies to appliances intended for outdoor installation. Provision of the heated

36、air may be by means of ducting or may be directly into the heated space. For Type C62and C63appliances, this European Standard only applies when such appliances are intended for final installation in a similar manner to Type C3appliances. This standard does not apply to: a) appliances intended for u

37、se in a single unit residential dwelling; b) appliances of the condensing type; c) appliances with atmospheric burners without a fan to assist the transportation of combustion air and/or flue gases; d) dual purpose air conditioning appliances (heating and cooling); e) appliances where the air is hea

38、ted by an intermediate fluid; f) appliances fitted with manual or automatic flue dampers; g) portable or transportable forced convection appliances; h) appliances having multiple heating units with a single draught diverter; i) appliances fitted with more than one flue outlet; j) appliances that are

39、 designed for continuous condensation within the flue system under normal operating conditions; k) appliances having combustion products evacuation ducts, POCEDs, that are non-metallic. This standard is applicable to appliances which are intended to be type tested. It also includes requirements conc

40、erning the evaluation of conformity, including factory production control, but these requirements only apply to POCEDs and their associated terminals. NOTE Requirements for appliances which are not type tested would need to be subject to further consideration. 2 Normative references The following re
