This European Standard shall be giv
27、en 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of an identical text or by endorsement, at the latest by May 2010, and conflicting national standards shall be withdrawn at the latest by May 2010.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 may be the
28、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 621:1998. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and support
29、s essential requirements of EU 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 621:1998. It has been prepared to incorporate requirements for combustion products evacuation ducts, POCEDs, sup
30、plied 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 B41 appliances. Furthermore, the opportunity presented by this revision has been taken to update the standard in
31、respect to EN 437:2003. NOTE For countries requesting special categories (specified in EN 437:2003), the absence of specific information concerning A.4.3 and A.4.4 implies that the general requirements described in the body of the standard (see 5.1.1, 5.2.2, 5.2.3 and 5.2.5) also apply to these spec
32、ial 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, Greece, Hungary, Iceland,
33、Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

34、) 5 1 Scope This European Standard specifies the requirements and test methods for the safety and efficiency of non-domestic gas-fired air heaters not exceeding a net heat input of 300 kW with (an) atmospheric burner(s) and without a fan to assist the transportation of combustion air and/or flue gas
35、es, hereafter referred to as “appliances“. This European Standard applies to Type B11, B41, C11and C31appliances intended for use in other than single unit residential dwellings. Provision of the heated air may be by means of ducting or may be directly into the heated space. This standard does not a
36、pply to: a) appliances intended for use in a single unit residential dwelling; b) appliances of the condensing type; c) appliances for outdoor installation; d) dual purpose air conditioning appliances (heating and cooling); e) appliances where the air is heated by an intermediate fluid; f) appliance
37、s with forced draught burners; g) appliances fitted with a manual or automatic means of adjusting the combustion air supply or the combustion products evacuation (including flue dampers); h) portable or transportable forced convection appliances; i) appliances having multiple heating units with a si
38、ngle draught diverter; j) appliances fitted with more than one flue outlet; k) appliances that are designed for continuous condensation within the flue system under normal operating conditions; l) appliances having combustion products evacuation ducts, POCEDs, that are non-metallic. This standard is
39、 applicable to appliances which are intended to be type tested. It also includes requirements concerning 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
40、 tested would need to be subject to further consideration. 2 Normative references The following referenced documents are indispensable for the application of this document.
