BS ISO 12472木制門組件的耐火性.膨脹型密封劑工效的測定方法-標準簡介
本標準規定了，用于測定膨脹材料或系統在木門組件門到框架間隙密封情況下的有效密封能力。膨脹密封延長了葉片邊緣和框架之間的縫隙滿足防火測試的完整性標準的時間，適用于與耐火1h以下的木材防火門配套使用的外露膨脹密封系統的效能評價。
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.
