The degradation of thermal performance, such as change in the activation energy and combustion rates arising from long-term storage of pyrotechnic substances, remains an unsolved challenge. We propose a novel technique for estimating the performance of pyrotechnic delays through non-calorimetric methods, exposed to a long-term heat and moisture conditions. Results of various spectroscopic methods such as Laser-induced Breakdown Spectroscopy, X-ray Photoelectron Spectroscopy, and X-ray Diffraction can go beyond the thermal performance changes traditionally suggested by the calorimetry and provide new information on the aging mechanism and compositional changes.
