Hello all, I was wondering if anyone knows of the origin of the 45 micro coulomb limit used to specify the charge of capacitance level under normal conditions for voltages up to 15 kV? Does this value come from scientific data or some other standard? Example standard clauses are: IEC 61010-1, clause 6.3.1 (c) (1) and IEC 60950-1, clause 2.4.2.
