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.
