是防风阀门吗?EN 1634-1 主要适用防火门和百叶窗,不在该标准的适用范围内,按只能参考测试哦。

EN1634-1 耐燃标准-适用范围:
-百叶门及旋转门;
-水平推拉门和立式拉门,包括链接推拉门,升华门;
-单层钢皮折叠式百叶窗;
-其他推拉折页门;
-倾斜门;
-卷帘门;
是否能承受4个小时耐火极限,通常需要根据完整性、隔热性判定是否符合,具体定义可参考如下:
耐火完整性:
在标准耐火试验条件下,建筑分隔构件当某一面受火时,能在一定时间内防止火焰和热气穿透或在背火面出现火焰的能力。
耐火隔热性:
在标准耐火试验条件下,建筑分隔构件当某一面受火时,能在一定时间内其背火面温度不超过规定值的能力
测试温度曲线:
根据标准规定控制时间—温度,不同时间不同温度显示如下:
1000°F (538°C) at 5 min
1462°F (795°C)at 20 min
1550°F (843°C) at 30 min
1700°F (927°C) at 1 h
1850°F (1010°C) at 2 h
2000°F (1093°C) at 4 h
