Shock Resistant Equipment

Shock Resistant Equipment

Shock Resistant Equipment

(OP)
I have an unusual question: Yesterday a co-worker gave me a hard copy of an email it read:

"Explosion Shock Resistant (ESR) = 12,000 psi per sec explosion shock resistant equipment rating"

We've had equipment rated for shock resistance before, but the units were in psi or pressure. I conducted an internet search on the acronym (ESR) and the words "explosion shock resistant" but the results I got were in psi not psi/sec.  In fact this looks like a pressure rate, judging by the units.  I conducted an internet search with NFPA and ASME and did fare any better.  I am not sure if I need to calculate the K value with this or what.  I thought it might be something similar to Blast Design, but I would need the standoff distance and, again, the units are wrong.  Does anybody here have any suggestions or clarifications?  Thanks in advance.
 

There are days when I wake up feeling like the dumbest man on the planet, then there are days when I confirm it.  

RE: Shock Resistant Equipment

It could be typo, or it could be a clever way to make a small number look bigger.  If their performance was only 6 kpsi, they can say that an explosiion occurs over, say, 0.5 s, so the shock that they're able to resist is 6kpsi/0.5s = 12kpsi/s.

I found this: http://www.stuvex.com/it/products-and-systems/categorie/explosion-resistance which uses the phrase explosion pressure shock resistant
