Abstract: The test method for the electric pyrotechnics is introduced, the test system of the electric parameter of pyrotechnics is built. The capacitor discharge ignition circuit for pyrotechnics is designed, the operating principle of the capacitor charge and discharge circuit and the formulas to calculate the main parameters are introduced, and the ignition circuit current is measured. The method of Four lines gradingtesting is proposed in the test of the variety bridge circuit DC resistance of pyrotechnics. The bridge wire meltdown time is determined though the variety of the ignition circuit voltage. The reliability and correctness of using this test system to measure electrical parameters of pyrotechnics are conformed. And it also offers effective ways to research of test for electrical parameters of pyrotechnics.
