BS ISO 12472木制门组件的耐火性.膨胀型密封剂工效的测定方法-标准简介

本标准规定了，用于测定膨胀材料或系统在木门组件门到框架间隙密封情况下的有效密封能力。膨胀密封延长了叶片边缘和框架之间的缝隙满足防火测试的完整性标准的时间，适用于与耐火1h以下的木材防火门配套使用的外露膨胀密封系统的效能评价。

This International Standard specifies a test method for determining the effective sealing capability of intumescent materials or systems in the context of sealing door-to-frame clearances in timber door assemblies. Intumescent seals extend the duration for which the gap between the leaf edge and the frame will isfy the integrity criteria of the fire resistance test, and sealing systems can be compared using this methe The method is suitable for evaluating the efficacy of exposed intumescent sealing systems used in conjunction ith timber fire resisting doors of up to 1 h fire resistance.
