Vorsphere™ Testing Standards
Testing bomb containment vessels properly ensures their effectiveness during an actual
An explosive containment rating is the amount of explosives a bomb resistant containment
vessel can contain during an explosion.
Testing guidelines that must be followed:
1. The HOSDB (Home Office Scientific Development Branch) in conjunction with the
CPNI (Centre for the Protection of National Infrastructure) have developed a Standard
by which devices of this nature are tested and rated. It determines the explosive
resistance and assesses the Mitigation of of any fragmentation.
2. Testing is conducted with C4 or PE4, manufactured to military specification, packed
to a specific density in order to ensure an accurate Protection rating is obtained.
3. Protection ratings are awarded on a scale of 1 to 10 stars. (1 being the lowest
rating and 10 being the highest standard available)
4. Since we cannot control where within a containment vessels an explosive device
will be placed, the following tests: bottom centre, bottom side wall, midpoint centre
and a fragmentation detonation are all required for determining an accurate explosive
