BS476-7标准为产品及材料的防火阻燃等级测试标准，BS476-7标准将防火等级划分为4个等级：BS476-7 Class 1；BS476-7 Class 2；BS476-7 Class 3；BS476-7 Class 4；一些特殊材料的BS476-7防火等级为Class 1R，南京睿督与您分享英标BS476-7防火等级Class 1R是什么情况？咨询电话：025-8658 3475。
英标BS476-7防火等级Class 1R是什么情况？
进行BS476-7,同时还要观察试验过程中样品燃烧的情况，如测试了6个以上的样品才完成BS476-7测试，则应在结果上加注“R”标记。因此许多达到BS476-7防火等级Class 1R的材料是加做了BS476-7测试。

ASTM C1104/C1104M-13a Standard Test Method for Determining the Water Vapor Sorption of Unfaced Mineral Fiber Insulation
ASTM C1104/C1104M-13a 测定表面未加工的矿纤维绝缘材料水蒸气吸收性的试验方法
1. ASTM C1104/C1104M标准适用范围
1.1 This test method covers the determination of the amount of water vapor sorbed by mineral fiber insulation exposed to a high-humidity atmosphere. This test method is applicable only to fibrous base material and binder. The results obtained by this test method cannot be used in describing faced products, since the facing is not tested by using this test method.
