For grinding processes and for paddle dryers with bars etc., the sensitivity of a product to shock has to be determined. A product is impact-sensitive and therefore explosible if it disintegrates with a bang upon its exposure to impact energy under given test conditions.

For a single test, the result is regarded as positive if the test sample burns or decomposes with detonation, flame (sparks) or development of heavy smoke.

Substances which detonate under the drop hammer are classed as explosives, and may not be milled in the plant.
