ISO 834-9非承重吊顶构件的特殊要求

ISO834-9建筑耐燃测定–名称概述

ISO 834-9 Fire-resistance tests-Elements of building construction-Part 9: Specific requirements for non-loadbearing ceiling elements
ISO 834-9 建筑构件耐火试验方法-第9部分:非承重吊顶构件的特殊要求

ISO834-9建筑耐燃测定–标准范围

ISO 834-9规定了确定下部受火的非承重吊顶构件耐火性能的试验程序,该类吊顶构件具有的耐火性能不受其上部任何建筑构件的影响。本部分适用于非承重吊顶构件,包括自支承式吊顶、悬挂式吊顶和简支式吊顶。
ISO 834-9标准不适用于作为水平防火分隔构件用以保护其上方承重构件的吊顶,该类吊顶构件的耐火性能可以按ISO 834-5。

ISO 834-9 specifies test procedures for determining the fire resistance of non-loadbearing ceiling elements, which possess fire resistance independent of any building element above them, when exposed to heating from below the ceiling. It is applicable to self-supporting ceilings and to ceilings suspended from, or fixed directly to, a supporting construction. It is not applicable to ceilings used as a horizontal fire barrier for the protection of a loadbearing element above, in which case performance is assessed as an integral part of the complete assembly using ISO 834-5。
