CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.This document supersedes CEN/TR 1749:2005.This technical report has been prepared under the aegis of the Sector Forum Gas Utilisation committee toprovide guidance to CEN Technical Committees who are preparing European Standards for appliancesburning combustible gases.It gives details of a general scheme for the classification of such appliances according to the method ofevacuating the products of combustion. It must be stressed that this scheme only concerns gas appliancesthat are intended to be installed within buildings. It does not apply to outdoor appliances. Nevertheless, it isrecognised that this appliance classification scheme could be utilised in other circumstances. For example, inthe case of :a) Appliances capable of utilising heating oil or kerosene, andb) Gas appliances intended for installation in a partially protected location external to a building.This form of appliance classification is widely used in the preparation of European Standards for gasappliances to identify the requirements and methods of test that are applicable to the various methods ofevacuating the products of combustion. Appliances classified in this way are generally described as “types”and this description has been retained for the purposes of this general scheme.The main purpose of the scheme is to promote harmonization in the classification of appliance types. Thisshould ensure that there is a clear understanding of the various appliance types and will avoid confusionarising from Technical Committees describing them in different ways. CEN Technical committees aretherefore requested to use this scheme in all circumstances in which it is appropriate. They should notdeviate from it unless there are sound technical reasons for so doing.In the preparation of this scheme it was noted that there were methods of evacuating products of combustionthat were particular to a specific Technical Committee or to a particular gas appliance. These particularmethods have not been included in the present scheme because, as indicated above, the main purpose of thescheme is to promote harmonization across Technical Committees.However, it is intended that this scheme should be reviewed from time to time in order to consider itsextension to other, possibly new, methods of evacuating products of combustion. At that time, such specificmethods of evacuating products of combustion may be included at the request of the Technical Committeesconcerned.【中国标准分类号】: Q82【国际标准分类号】: 91_140_40【页数】: 36P.;A4【正文语种】: 英语
