Hot Spots
This term denotes the increase of the detonation sensibility of explosives
by finely dispersed air bubbles. The loss in sensitivity to
detonation of gelatinous nitroglycerine explosives by long storage has
been known since the time of Alfred Nobel; it is due to the loss or
coagulation of the air bubbles that may have been left in the explosive
by the manufacturing process. This effect can be explained by the
adiabatic compression and heating of the air inclusions as the detonation
wave is passing (W Detonation, wave theory) and is termed “hot
spots”. This effect was used to make the recently developed cap
sensitive W Emulsion Slurries. Conservation and independence from
pressure of the air inclusions can be achieved by so-called W Microballoons.
Hot Storage Tests
Warmlagertest; épreuves de chaleur
These tests are applied to accelerate the decomposition of an explosive
material, which is usually very slow at normal temperatures,
able to evaluate the stability and the expected service life of the
material from the identity and the amount of the decomposition prod-
