ISO834-6建筑耐燃測定–名稱概述
ISO 834-6 Fire-resistance tests-Elements of building construction-Part 6: Specific requirements for loadbearing beams
ISO 834-6 建筑構件耐火試驗方法-第6部分:梁的特殊要求。
ISO834-6建筑耐燃測定–標準范圍
ISO 834的這一部分規定了梁在單獨測試時確定其防火性的程序。
通常情況下,梁的測試是底面和完全暴露的兩個垂直側面受火。但是,當曝光從四面或少于三面時,適當的改變受火條件是必要的。梁是樓板結構的一部分,應該結合ISO 834-5中描述對樓板結構進行測試,并對其完整性和絕緣性進行評估。
This part of ISO 834 specifies the procedures to be followed for determining the fire resistance of beams, when tested on their own.
Beams are normally tested with their underside and two vertical sides fully exposed to heating. However, when the exposure is from four sides or less than three sides, appropriate exposure conditions are necessary. Beams which are part of a floor construction are tested with the floor construction as described in ISO 834-5 and are subject to evaluation of integrity and insulation.
