35、 has been prepared by Technical Committee CEN/TC 109 “Central heating boilers using gaseous fuels”, the secretariat of which is held by NEN. 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 Februar

36、y 2007, and conflicting national standards shall be withdrawn at the latest by February 2007. It was established to deal with aspects related to: safety; rational use of energy; fitness for purpose. Other types of boilers are dealt with in separate standards. This European Standard has been prepared

37、 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 relationship with EU Directives 90/396/EEC “Approximation of the laws of Member States concerning gas appliances” and 92/42/EEC “Efficiency re

38、quirements for new hot water boilers fired with liquid or gaseous fuels” see informative Annex ZA, which is an integral part of this European Standard. This standard covers only type testing. Boilers within the scope of this European Standard are typically installed in a room separated from living r

39、ooms and provided with appropriate ventilation directly to the outside. They need not be fitted with a combustion products discharge safety device but appropriate warnings on the packaging and in the instructions should clearly indicate the limit on the use of this type of boiler. It is impractical

40、to use the full range of test gases to EN 437 for type testing since their availability, for inputs over 300 kW, may present problems for test houses and manufacturers. Informative Annex L gives guidance on the use of gases for tests in order to ensure conformity with EU Directive 90/396/EEC “Approx

41、imation of the laws of Member States concerning gas appliances.” According 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, Fran

42、ce, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 13836:2006 (E) 7 1 Scope This European Standard specifies the requirements and test metho

43、ds concerning, in particular, the construction, safety, fitness for purpose, and rational use of energy, as well as the classification and marking of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners or fully premixed burners, and are hereaf

44、ter referred to as “boilers”. This European Standard applies to boilers of type B, as listed in 4.2: that use one or more combustible gases of the three gas families at the pressures stated in Tables 16 and 17; that have a nominal heat input (on the basis of net calorific value) exceeding 300 kW, bu

45、t not exceeding 1 000 kW, including modular boilers; where the temperature of the heat transfer fluid does not exceed 105 C during normal operation; where the maximum operating pressure in the water circuit does not exceed 6 bar; that can give rise to condensation under certain circumstances; of the

46、 standard and low-temperature types. This European Standard applies to boilers designed for sealed water systems or for open water systems. This European Standard does not contain all the requirements necessary for boilers: intended to be installed in the open or in living rooms; permanently fitted

47、with more than one flue outlet; where the combustion circuit is sealed with respect to the room where the boiler is installed; of the condensing type; intended to be connected to a common flue having mechanical extraction; fitted with a forced draught burner in accordance with EN 676 (see EN 303-7);

48、 producing hot water for domestic purposes. This standard only covers type testing. Matters related to quality assurance systems, tests during production, and certificates of conformity of auxiliary devices are not dealt with in this European Standard. EN 13836:2006 (E) 8 2 Normative references The

49、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 referenced document (including any amendments) applies.
