The equation for type 3 explosives is in annex F. This has the HSE logo on it so should hold some weight with them.

Although that particular analysis was conducted by Burgoyne & Partners, I believe that the methodology is relatively straightforward.

Roy Merrifield, Roland Wharton. Measurement of the Size, Duration and Thermal Output of Fireballs Produced by a Range of Propellants. Propellants, Explosives, Pyrotechnics. September 2000. Volume 25, Issue 4, Pages 179-185.

They are just in the process of updating the STANAGs for all IM test procedures and hold other useful data.

We have used them previously on an HSE licence project relating to HT3 fireball projection and mitigation.

The review provided document and test form the Health and Safety Laboratories with data to support fireball radii.
If you’d like to contact me for a chat more than happy to go through what I’ve been doing.

Can you give me some more information about the materials and applications you are interested in?
