EN 1366的本部分规定了一种测定安装在防火分隔元件中的非机械防火屏障耐火性的方法，该防火分隔元件设计用于承受高温下的热量和烟和气体的通过。本欧洲标准与EN 1363-1和EN 1366-2结合使用。本欧洲标准不适用于在未经修改的情况下测试吊顶内的非机械防火屏障。本欧洲标准不适用于测试防火阀，见EN 1366-2。本欧洲标准不适用于测试空气传输格栅等产品，因为所涉及的压力和流量不同，可能导致不同的行为。

This part of EN 1366 specifies a method for determining the fire resistance of non-mechanical fire barriers installed in fire separating elements designed to withstand heat and the passage of smoke and gases at high temperature. This European Standard is used in conjunction with EN 1363-1 and EN 1366-2. This European Standard is not suitable for testing non-mechanical fire barriers in suspended ceilings without modification. This European Standard is not suitable for testing fire dampers, see EN 1366-2. This European Standard is not suitable for testing such products as air transfer grilles, as the pressures and flows involved are different and may cause differing behaviour.
