Single-base propellants contain a single energetic component: nitrocellulose. Accurate predictions of propellant shelf-life should result in cost savings in terms of human and material resources. This study derived an optimized kinetic model reaction order that described stabilizer consumption and estimated propellant shelf-life. High temperature accelerated aging tests gave an optimum reaction order value of 1.15481, from which the minimum standard error of a linear regression estimate of 16.284 was obtained. At normal storage temperature of 21 – 30°C,propellants should have a safe shelf-life of 140 years, and a minimum of 35 years. It is necessary to consider thetemperature range in ammunition storage areas to predict propellant shelf-life more accurately.
