The blasting cap test is utilized to evaluate the explosion potential of propellants by examining the degree of damage and deformation of the aluminium tube. The explosion hazard level is divided into three categories: safe, low explosion, and high explosion. However, this qualitative categorization has a limitation that it is not based on an actual measurement of explosion quantities. To overcome this, we carried out quantitative internal pressure measurement by mounting a pressure sensor on the outer drum. It was confirmed that the present blasting cap test configuration can effectively measure the explosive pressure for the distilled water, ammonium nitrate, and explosive composition of ethanol blended hydrogen peroxide. As a result, the blasting cap test method proposed in this study could be helpful in propellant development in terms of quantitatively measuring and comparing the explosive power of propellants.
