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 produced by high explosives in an arena test. The loading categories are defined by pressure and impulse parameters and represent free-field high explosive events caused by:
- 3 kg to 20 kg (TNT equivalent) at stand-off distances from 3 m to 9 m, described by the fixed loading levels PXR 1 to PXR 7;
- 100 kg to 500 kg (TNT equivalent) at stand-off distances from about 15 m to 30 m, described by the fixed loading levels VXR 1 to VXR 7.
It produces a classification according to prEN 13123-2:2023.
Scenarios characterized by specified blast parameters for other high explosive scenarios, can also be specified.
Blast loads which cannot be produced in an arena test might be produced by a shock tube test following prEN 13123-1:2022 and prEN 13124-1:2022.
This document is applicable to blast waves generated by explosions in an arena test facility to produce high explosive blast loads on windows, doors and shutters as well as curtain walling systems, complete with their frames, infills and fixings, for use in both internal and external locations in buildings. It gives no information on the explosion resistance capacity of the wall or other surrounding structure.
This document covers only the behaviour of the complete test specimen 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, 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. It gives no information on the behaviour of the test specimens subjected to other types of loading.
