The products aremanufactured in the form of boards or rolls or other preformed ware.This European Standard specifies product characteristics and includes procedures for testing, evaluation ofconformity, marking and labelling.Products covered by this European Standard are also used for sound insulation and in prefabricated thermalinsulation systems and composite panels; the performance of systems incorporating these products is notcovered.This European Standard does not specify the required class or level of a given property to be achieved by aproduct to demonstrate fitness for purpose in a particular application. The classes and levels required for agiven application are to be found in regulations or non-conflicting standards.Products with a declared thermal resistance lower than 0,25 m2?K/W or a declared thermal conductivity at10 °C greater than 0,060 W/(m·K) are not covered by this European Standard.【中国标准分类号】: Q25【国际标准分类号】: 91_100_60【页数】: 52P.;A4【正文语种】: 英语 | 欢迎光临 世界资料网论坛 (http://bbs.infoeach.com/) | Powered by Discuz!
