European Standard EN13123-2 specifies the criteria which windows, doors and shutters shall satisfy to achieve a classification when submitted to the range test method described in EN 13124-2.

This European Standard concerns a test method against blast waves in open air resulting from high explosives that can be carried by hand and placed a few metres from a target.  At such close distances blast values vary across an attack face.  Controlled measurement of the actual blast on the face of the test specimen being difficult, costly and subject to inaccuracy, consistency of the blast forces is therefore controlled in this European Standard by the characteristics of the explosive charge and its location.

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 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 can be required (see clause 4).

This European Standard gives no information on the explosion resistance capacity of the wall or other surrounding structure.
