GB 31247—2014电缆及光缆燃烧性能分级与欧盟CPR法规差异对比

Comparison of the Differences Detween GB 31247—2014 Cable and Optical Cable Burning Performance Classification and EU CPR regulations

针对国家标准GB 31247—2014《电缆及光缆燃烧性能分级》和欧盟CPR法规对电缆及光缆燃烧性能分级的差异进行对比分析,包括燃烧性能等级、燃烧性能附加等级、欧盟分级测试细节解析及分级标识等,以期电缆及光缆相关从业人员能正确区分国家标准与欧盟CPR法规的差异,设计的电缆及光缆产品能满足对应标准的要求。

According to the national standard GB 31247—2014"classification of combustion performance of cables and optical cables"and the European Union CPR regulations,including combustion performance level,combustion performance additional level,detailed analysis of EU classification test and classification identification,etc.,the differences in the classification of cable and optical cable combustion performance were compared and analyzed.It was hoped that the relevant practitioners of cables and optical cables could correctly distinguish the differences between national standards and EU CPR regulations,and the designed cables and optical cable products could meet the requirements of corresponding standards.
