本欧洲标准规定了烟雾控制系统部件分类程序，采用在相关测试方法应用范围内的耐火试验数据。在扩展应用测试结果的基础上进行分类也包括在本欧洲标准的范围内。 本欧洲标准涵盖的产品有: - 烟控制管道; - 烟雾控制阻尼器; - 烟幕; - 动力烟气和排热通风机（风扇），包括连接器; - 天然烟气和排烟通风机。 相关文件，包括为这些产品准备的相关测试方法，列于第2条

This European Standard specifies the procedure for classification of components of smoke control systems, using data from fire resistance tests which are within the field of application of the relevant test methods. Classification on the basis of extended application of test results is also included in the scope of this European Standard. Products covered by this European Standard are: - smoke control ducts; - smoke control dampers; - smoke barriers; - powered smoke and heat exhaust ventilators (fans), including connectors; - natural smoke and heat exhaust ventilators. Relevant documents which include the relevant test methods which have been prepared for these products are listed in Clause 2.
