The Construction of the Friability Test at TNO-PML

Abstract

In co-operation with SNPE, France, the friability test has been constructed. This test is applied to determine the effect of impact on an explosive substance which is a candidate to be assigned as an Extremely Insensitive Detonating Substance (EIDS). In this test a sample is directed against a steel plate at a velocity of about 150 m/s by using a gas gun. After having performed this test, the explosive is tested in the closed vessel test to assess any changes in the burning characteristic, i.e. the peak pressure and pressure rise rate, due to the impact. The volume of the existing closed vessel needed to be adjusted in order to fulfill the calibration requirements with respect to peak pressure (80 +/- 0.2 MPa) and pressure rise rate (not more than 15.2 +/- MPa/msec). This calibration was performed using a reference propellant delivered by SNPE. It appears that neither calibration requirement could be met by the closed vessel. The requirement for the peak pressure could be fulfilled, but not for the pressure rise rate.
