limits of the nominal rating. Capacitance measurement
shall be made by means of a polarized capacitance bridge.
No polarizing voltage is required. The maximum voltage
applied during measurements shall be 0.5 volt rms at 100 Hz
and + 25°C.

applied, capacitors shall meet the requirements in table
below.
3. Reverse Voltage: These capacitors are capable of
withstanding peak voltage in the reverse direction equal
to:
