what?
ASTM ANS - The organization that develops standard methods for testing materials
Auto-ignition ANS - Initiation of combustion by heat but without a spark or flame
Backdraft ANS - A deflagration resulting from the sudden introduction of air into a confined space
containing oxygen-deficient products of incomplete combustion
Backdraft ANS - An explosion caused by a combination of combustible materials heated to the ignition
point and a sudden introduction of oxygen to support combustion
