An explosion triggered by explosive substances or a chemical spill demands blast resistant windows, doors and facades to keep people and investments safe.
Explosions in chemical plants produce blasts with comparatively low overpressure (about 5 to 100 kPa) and exposure time up to 500 msec. Commercial explosives or IED’s (Improvised explosive device) induce explosions usually much higher over pressures (up to about 10 GPa) coupled with short exposure time.
Requirements of the blast resistant constructions also vary considerably according to load size and distance from structure. Contact detonations for example induce entirely different strains than explosions in far field.
This results in different constructional systems as well as test and calculation procedures. Successful tests following ISO 16933 have been conducted in outdoor, shock tube and with contact detonation. Our explosion resistant and blast resistant structures can also be combined with break-in resistance, fire arm resistance and fire protection.
