Determination of Heat Sensitivity

The application of heat for the initiation of explosives can be realized in two ways  

1) By local heating of an explosive by a heat source in the form of a flame, spark, etc. A localized thermal impulse creates a local zone in which reactions start to occur and then propagate through the rest of the explosive due to their self-sustaining character.

Foods rich in fat or moisture are difficult to grind or disintegrate in their intact state. Predrying and defatting are often used as a pretreatment, except for the determination of heat-sensitive and easily oxidated components such as vitamins.
