Page 4 1 Scope EN 131 24-1 12001 This European Standard specifies a conventional test procedure to permit classification of the explosion resistance of windows, doors and shutter together with their infills. This European Standard concerns a method of test against blast waves generated by us
18、ing a shock tube facility to simulate a high explosive detonation in the order of 100 kg to 2 500 kg TNT at distances from about 35 m to 50 m . 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
20、ading. NOTE which is at least equal to that of the window or door. Care should be taken to ensure that all joints between the wall and the window or door have protect. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
