UNE-EN 13124-1:2026

This document specifies a conventional test procedure to permit classification of the explosion resistance of windows, doors, shutters, together with their infills, as well as curtain walling elements.This document concerns a method of test against blast waves generated using a shock tube facility to simulate detonation events. This document considers high explosive detonations in the order of 100 kg to 2 500 kg TNT equivalent at distances from about 35 m to 50 m, described by the fixed loading levels EPR0 to EPR4. Scenarios characterized by variable blast parameters for further high explosive detonations and gas or chemical explosions can also be specified.This document covers only the behaviour of the complete test specimen including infill, frame and fixings as tested.This document gives no information on the ability of the surrounding wall or building structure to resist the direct or transmitted forces.If the windows, doors, shutters and curtain walling components are intended for specific conditions of climate, specific test conditions can be required.Requirements for the performance of opening and locking mechanisms or for testing in an open condition can also be specified.This document gives no information on the behaviour of the test specimens subjected to other types of loading.
