This standard is issued under the fixed designation E 1488; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This test method covers the determination of the minimum temperature at which a dust cloud will
autoignite. The dust cloud is exposed to air heated to various temperatures in a furnace. Ignition of the
cloud is indicated by visual observation of the flame. The chemical nature of the dust as well as its
concentration, particle size, moisture, and surface area affects the results.
