E = (PV / k-1) x (1-(Patm / P)k-1/k, where:
E = Energy in Joules
P = Absolute pressure in Pascals
V = Test volume in M3
Patm = Atmospheric pressure in Pascals
k = Ratio of specific heat of air
Then convert to TNT:
TNTlb = E x 4.8 x 10-7
The safe distance can then be calculated by: SD = 15 (TNTlb).5
I use this for calculating safe working distance for all pnuematic tests. There are similar for hydrotests, but the stored energy is obviously a whole lot less.

E = (PV / k-1) x (1-(Patm / P)^k-1/k,
and
SD = 15 (TNTlb)^.5

I'm assuming that TNTlb is equivalent weight in pounds.
What units for SD ?
Cheers

Greg Lamberson's equations may be better than mine.
