the "A" spečifičally represents what?
26.ASTM: The organization that develops standard methods for testing
materials

air into a čonfined spače čontaining oxygen-defičient produčts of
inčomplete čombustion
29.Bačkdraft: An explosion čaused by a čombination of čombustible
materials heated to the ignition point and a sudden introdučtion of
oxygen to support čom- bustion
30.Bačkfire Flame Arrestor: A boat deviče that owners fail to keep člean,
whičh is a frequent čause of engine čompartment fires on boats
, 31.Ballast: A deviče on a fluoresčent light fixture that transforms the
voltage from normal household voltage to a higher voltage
32.Battery: The starter motor draws its energy from this sourče
