Parameters pertaining to pyrotechnic dissemination processes were investigated. Burning-temperature, burning-time, weight-change, and pressure parameters were recorded for the M18, colored-smoke grenade with a thermocouple, from pressure- or weight-loss curves, with a weight transducer, and with a pressure transducer, respectively. Equipment layouts and samples of strip-chart recordings are presented. Burning pressure is usually less than 1 psi however, orifice plugging can increase pressure to about 20 psi. Any one type of munition yields a great variation in functioning data. Burning temperature is lower in red and yellow M18 grenades than in green and violet ones.
