R. Meyer J. Köhler A. Homburg Explosives

Booster Sensitivity Test
a rocket device that accelerates the missile to attain the required
speed after the start.
Booster Sensitivity Test
The booster sensitivity test procedure is a scaled-up modification of
the Bruceton Test (unconfined charge). The source of the shock
consists of two Tetryl pellets, each 1.57 inches in diameter and 1.60
inches long, of approximately 100 g total weight. The initial shock is
degraded through wax spacers of cast Acrawax B, 1–5/8 inches in
diameter. The test charges are 1–5/8 inches diameter by 5 inches
long. The value given is the thickness of wax in inches at the 50%
detonation point. The weight of the Tetryl pellet noted is the minimum
which will produce detonation with the spacer indicated.
