摘要：
The total charge on a charged sheet before and after a provoked brush discharge, their difference "C', the induced charge "A" on different probes immediately before the discharge and their transferred charge "B" measured by commercially available Coulombmeters have been measured for probes from 2 mm to 25 mm in diameter including human thumb and shielded probe. The brush discharges were provoked on PTFE discs 10 cm-20 cm. The results obtained can be used for correct estimation of the incendivity of brush discharges between 10 nC and 90 nC.
