Zusammenfassung

In determining the relative hazards associated with various vapor-air mixtures in contact with a specific surface at a particular temperature and pressure, the Bureau of Mines has in the past employed the standard ASTM autogenous ignition temperature apparatus (ASTM Designation D 286-30) as well as a modification of this apparatus. Since only one electric heater was used in this modified apparatus, there was a temperature differential along the axis of the test flask. Moreover, because of the large amount of metal used in the construction of this apparatus, 1 or more hours often were required to change the temperature between successive tests. Accordingly, a new ignition temperature apparatus (I-8) has been developed which makes the determination of minimum spontaneous ignition temperatures-autogenous ignition temperatures-more rapid, accurate, and economical.
