摘要
介绍了材料燃烧烟气毒性的试验方法、试验设备和试验要求,以及电缆燃烧烟气毒性的评价,并给出了常用无卤阻燃绝缘材料和护套材料的烟气毒性水平和危险分级。分析了以烟气浓度(mg/L)为单位的致死浓度与以材料质量(g)为单位的致死浓度LC50值的关系。
:This paper presents the test method, test apparatus and test requirements for the toxicity of smoke from burning materials as well the toxicity evaluation of the smoke evolved from a burning cable. The authors gave the hazardous level classification for the toxicity of smoke from commonly-used halogen-free insulating and sheathing materi- als and analyzed the relationship between the lethal concentration in terms of smoke density ( in mg/L) and the half lethal concentration LC^o in terms of mass of material ( in g).
