ISO834-9建筑耐燃測定–名稱概述
ISO 834-9 Fire-resistance tests-Elements of building construction-Part 9: Specific requirements for non-loadbearing ceiling elements
ISO 834-9 建筑構件耐火試驗方法-第9部分:非承重吊頂構件的特殊要求
ISO834-9建筑耐燃測定–標準范圍
ISO 834-9規定了確定下部受火的非承重吊頂構件耐火性能的試驗程序,該類吊頂構件具有的耐火性能不受其上部任何建筑構件的影響。本部分適用于非承重吊頂構件,包括自支承式吊頂、懸掛式吊頂和簡支式吊頂。
ISO 834-9標準不適用于作為水平防火分隔構件用以保護其上方承重構件的吊頂,該類吊頂構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。
