摘要
从电缆及光缆燃烧性能分级的必要性出发,详细介绍我国首次发布的国家标准GB 31247-2014《电缆及光缆燃烧性能分级》的编制背景、编制原则、特点及主要内容:电缆及光缆燃烧性能等级、燃烧滴落物/微粒附加分级、烟气毒性附加分级、腐蚀性附加分级。
Starting from the necessity of classification for burning behavior of electrical and optical cables, the paper introduces the preparation background, preparation principle, characteristics and main contents of the national standard Classification for Burning Behavior of Electrical and Optical Cables （GB 31247- 2014） issued for the first time in China. The standard mainly provides classification for burning behavior of electrical and optical cables, additional classification for flaming droplets/particles, additional classification for smoke toxicity and additional classification for corrosivity.
