The output characteristics of four different logs of M42 Percussion Caps have been studied with a high-speed, broad-band, two-color optical pyrometer UVIR Radiation Output Detector. The output characteristics studied were the relative energy history, the temperature history, relative brisance, and blast pattern. Lots WWC 358 and WWC 1-15 exhibited low brisance, long, sustained, burning activity, and coruscation in the output. Lot PA-101 exhibited high brisance, little burning, and no coruscation. Lot 100 exhibited low brisance, little burning, and no coruscation. The burning temperature of all four lots was in the range of 2500 to 2700 Kelvin.
