SUN IGNITION SENSITIVITY OF BASE GRAIN
Abstract
Ignition of casting powder exposed to the sun in yelaluminum-foil- lined) ''Leverpaks'' occurs when the casting powder is heated to its auto ignition temperature through the focusing of the sun's rays by the foil-lined walls. The minimum height of exposed wall of a yellow Leverpak nec essary to focus the sun's rays on the powder and produce ignition is 6 inches. Exposure to the sun of casting powder in blue (paper-lined) ''Leverpaks'' does not focus the sun of the pow der. Single-base casting powder is less sensitive to ignition in this manner than double-base or modified double-base casting powder; however, single-base powders are still sensitive.
