The report reviews electrostatic sensitivity testing methods and techniques used at the Explosives Division, Feltman Research Laboratory, Picatinny Arsenal, and the Naval Ordnance Laboratory. The advantages and disadvantages of the present methods are discussed with the emphasis on the appropriateness of each method in determining a minimum energy for initiation. The properties of the electric discharge circuits, particularly the effects of the series resistances and storage capacitors on discharge rate that govern the energy delivery to the spark gap, are analyzed. To develop testing procedures that will yield a more meaningful characterization of the sensitivity of primary explosives, a testing methodology that involves the use of a sensitivity map, a type of response surface, is introduced.
