This standard defines the criteria which windows, doors and shutters shall satisfy to achieve a classification when submitted to the test method described in EN 13124-2: Windows, doors and shutters - Explosion resistance - Test method - Part 2: Range test. This 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 deificult, costly and subject to inaccurancy, consistency of the blast forces is therefore con
