Real Electrostatic Sensitivity Tests for 105 Electric Primers

This paper briefly introduces the method of testing the real sensitivity for EED and gives the data processing method in terms of the electrostatic critical ignition energy of conductive powder EED conforming to logarithmic normal distribution. In light of the above, the real electrostatic sensitivities of 105 electric primers are tested and the confidence interval of its minimum electrostatic ignition energy is determined.
