The Identification and Safe Life Prediction of Hazardous Materials,
Abstract
A suitable test for measuring the relative thermal stability of propellants containing nitrate esters is important not only for production controls, but also in defining the time and temperature at which this formulation can be safely stored. Over the years a number of tests have been developed for this purpose. However, most of these methods require either too much time or too sophisticated equipment to be implemented into process control. This report explains an isothermal time to autoignition method which is presently being used to identify potentially hazardous materials, and the ozawa method of predicting the half life of these substances. Other methods of identifying hazardous materials and predicting safe life are presented along with the reasons these technique are not being utilized at Thiokol/Wasatch.
