Recommendation on assessing flame spreading of materials using ISO 9705

Abstract

虽然性能化规范尚未达到通用的程度 ,但中国香港建筑业消防安全条款已用于“工程方法”设计中 ,在回顾了四个标准试验 ,即 ASTM E1 32 1 - 97a、BS4 76 :Part:1 997、ASTM E84 -99/ NFPA2 5 5和 ISO970 5 :1 993(E)之后 ,介绍了 ISO970 5 ,供地方政府评估各种材料的火焰传播。为妥善处理新的建筑材料 ,应将材料和构件的火焰传播试验列入说明中 Fire safety provisions for buildings in Hong Kong can be designed with the "engineering approach", though the performance-based fire code is not yet available. To cope with the use of new building materials, flame spread tests on materials and components should be specified. After reviewing four standard tests in the literature, i.e. ASTM E1321-97a, BS476: Part 7:1997, ASTM E84-99/NFPA 255 and ISO 9705:1993(E), the ISO 9705 is recommended to the local government for assessing the spread of flame over materials.
