The Defender Range Blast Resistant Buildings where design approval for the structure of the unit has been designed and manufactured to meet the blast resistance criteria under the following conditions:
• Walls – Reflected overpressure of 650 mbar for a positive phase duration on 100msec
• Roof – The roof for the 650mbar module (reflected on the front face) would need to be able to resist the 320mbar pressure (side on or overpressure) for the duration of 100msec
• Floor– Reflected overpressure of 650mbar for a positive phase duration of 100msec
• Windows – Reflected overpressure of 650mbar for a positive phase duration of 100msec
• Door – Reflected overpressure of 650mbar for a positive phase duration of 100msec
• Door has been classified as Category 1
All Blast loadings assumed to be of a shock wave form i.e instantaneously rising at time t=0 to the maximum overpressure and decaying linearly to zero mbar at t=100msec
