P.S. If the capacitance value is less than the
minimum value permitted, then after the other
measurements have been made the capacitor shall
be precondition according to “IEC 60384 4.1” and
then the requirement shall be met.

Specified stress voltage applied for 1~5 seconds
Voltage Proof
4.6
No breakdown or flashover
Ur ≤ 100 V: series applied 2.5 Ur
100 V < Ur ≤ 200 V series applied
(1.5 Ur + 100)
200 V < Ur ≤ 500 V series applied
(1.3 Ur + 100)
Ur > 500 V: 1.3 Ur
Ur ≧ 1000 V: 1.2 Ur
Charge/Discharge current is less than 50 mA
