Several European standards cover the resistance of building doors, windows and shutters to attacks involving explosives.
EN 13123-1 lays down the requirements and classification used in the standard (resistance levels)
EN 13124-1 contains the test methods used to measure resistance to explosives
These standards cover the resistance of hardware to the excess pressure of a blast created by a shock tube. This tube is used to simulate a powerful detonation of explosives equal to a charge of between 100 kg and 2,500 kg of trinitrotoluene (TNT) at distances ranging from 35 to 50 metres from the test element.
