This European Standard covers only the behaviour of the complete unit including infill, frame and fixings as tested. It gives no information on the ability

19、of the surrounding wall or building structure to resist the direct or transmitted forces. If the windows, doors and shutters are intended for specific conditions of climate, specific test conditions may be required. It gives no information on the behaviour of the units subjected to other types of lo
