DEVICE FOR TESTS OF PYROTECHNICAL COMPOSITION Russian patent published in 2003 - IPC

FIELD: study of electrical phenomena becoming apparent at burning, and check-up of the quality of manufacture of pyrotechnical compositions condensed systems producing conducting combustion products (slags) at burning. SUBSTANCE: the device has a specimen of the tested pyrotechnical composition, inflammation unit and two electrodes connected to the specimen at a different distance from the inflammation unit, even one electrode is made of solid combustion products (slag) of the tested pyrotechnical composition. The free ends of the electrodes are connected to a measuring instrument detecting the electric signal arising at burning of the specimen. EFFECT: enhanced accuracy of measurement of emf of burning due to reduction to zero of parasitic emf. 3 dwg _
