We are conducting a wide variety of studies concerning explosion safety - ranging from basic to applied - by advancing the understanding of ignition and explosion phenomena of high energy substances that are representative of explosives. These studies include safety assessment methods and safety technologies, techniques for reducing explosion effects, and technologies for effective utilization of energetic materials.
In addition, we are actively responding to government needs for explosives by executing large-scale explosion tests in the field. The results obtained are reflected in both creating standards for safe handling techniques of explosives and establishing the formulation of standards for handling internationally hazardous substances through improvement of UN Manual of Tests and Criteria, thereby contributing to the realization of a safe and secure society.

Explosibility Evaluation Based on Exothermic Decomposition Energy
Development of method to measure exothermic decomposition energy for evaluation of explosibility of chemical substances (JIS K4834)
For over 50 samples of explosives (energy substances), we conducted consistent measurements of the exothermic decomposition energy based on JIS K4834.
→ We clarified the relationship between exothermic onset temperature and exothermic decomposition energy.
