(OP)
Greetings,
I have posted this question in the mechanical engineers' forum. However, I'd feel that it may be more applicable here since it is product specific. What is the maximum combustible pressure for gum arabic? I am checking a design of a dust collector and gum arabic is the product collected. The collector is to meet NFPA 69 standards, which is the origin of the question. Any information, vaules, or leads will be greatly appreciated. Thanks.

I assume that you are referring to Table T.B. 1.2.4 Hazard Classes of Dust Deflagrations, correct?

For gum arabic the following are listed. This only applies to a dust passing through a No 200 US Standard size sieve at a concentration of 0.50 oz per cu ft, see Bureau of Mines R.I. 5624 (1960)
Ignition temp of dust cloud 500 deg C
Min spark for ignition 100 joules
Min explosive conc. 0.060 oz/cu ft
Max explosion pressure 84 psig
Max rate of pressure 1500 psi/sec
Dust Classification ST-1

However, shock waves could cause higher local pressures.
