Abstract : Pyrotechnic compositions which have delay, igni ter, flash, and signal applications were submitted for investigation with regard to their impact and friction sensitivity characteristics. Impact tests were conducted in accordance with the technique described in Technical Report FRLTR-25 except that the samples were tested as received, without performing the granulation specified. Friction tests were conducted in accordance with the procedure outlined in Picatinny Arsenal Testing Manual 7-1. Extreme sensitivity to both the friction and impact tests was found to be a function of the particular ingredients and the particle size of those ingredients. In general, the perchlorate containing compositions were found to be extremely sensitive to both friction and impact. The same is generally true of compositions containing finely divided fuels such as boron, zirconium, potassium borohydride, aluminum, magnesium, and calcium and its alloys. Organic additives in the form of binders or color intensifiers generally do not decrease and may increase sensitivity to both impact and friction when used in moderate amounts.
