SAFETY INFORMATION FROM PROPELLANT SENSITIVITY STUDIES
Abstract
Results of work on the Propellant Sensitivity Project with emphasis on the use of gap test and other small scale tests for safety studies are discussed. Measured initiating pressures were highest near the critical diameter of the test material and decreased to their lowest value at an effectively infinite acceptor diameter. The standard confinement of the gap test increased the effective acceptor diameter by a factor of 2.5 for Comp B. Gap test results showed good correlation with large-scale field tests, bluntnosed bullet tests, and the approximately onedimensional wedge test results; it is believed that the gap test measures a 50% initiating pressure close to that for an infinite diameter acceptor. A supplement to the NOL Shock Sensitivity Test for propellants was devised whereby the judicious choice of explosive witness systems makes it possible: (1) to assess the strength of reactions of too low impulse to produce a positive result under the conditions of the standard test, and (2) to measure the sensitivity to shock initiation of substances exhibiting such reactions.
