Air blast experiments with a small amount of spherical RDX were carried out. 10g to 70g RDX charges were detonated by lead azide in contact with on electric heater. Generated blast waves (peak normally reflected overpressure) were measured by piezoelectric gauges located at less than two meters. The peak overpressures were processed with Hopkinson's scaling law and they were compared with past data which had been obtained by representative experiments that ranged from a kilogram to tons of high explosives.
The results described the Hopkinson's scaling law that could be applied to a small charge of explosives at a short distance.
We confirmed that the law for peak overpressure was valid between the present results and large scale experiments.
