Thom, I agree with that.
It's why I asked if anybody knows about any successful or
unsuccessful tests with hi-ex and aerosol canisters,
either by FM, UL or any other recognized testlab, to get a clear picture.
Yes, may be our well-respected colleague Joe feels tempted to share his views?

The FM data sheets are the result of their testing, and I believe that the
ESFR or high density area's and specific head temp's are the only way they
recommend protection of these commodities. If they don't list foam, then it
is either because they don't recommend it or haven't tested it with these
products.
Joe H. are you out there? Any insider info on this?

Subject: RE: Aerosols and hi-ex foam
Thom,
The FM datasheets didn't help me any further:
FM 7-31 does not mention foam at all.
FM 4-3N has only 3 pages and points to NFPA 11A.
I'm open for other suggestions...
