摘要
介绍国内外防火阻燃线缆的测试标准,以及国家标准GB50311-2007《综合布线系统工程设计规范》和GB50174-2008《电子信息系统机房设计规范》对通信线缆的阻燃要求;指出电气设计不能仅注明"阻燃",而应注明线缆的阻燃等级。
Test standards for fire-proof and flame-retardant wires or cables at home and abroad and requirements for flame-retardant of communication cable specified in Code for Engineering Design of Generic Cabling System （GB 50311-2007） and Code for Design of Electronic （GB 50174 - 2008） are indicated that not only the flame-retardant rating during electrical design. Information System Room introduced. Besides, it is ＂flame retardant＂ but also of cable should be marked
