One flame application

After removing test flame from capacitor, the

capacitor must not continue to burn for more

than 10 s. No burning particle must drop

from the sample.

SUB-GROUP C7

4.18

Active flammability

20 cycles of 2.5 kV discharges on the test

capacitor connected to URac

The cheese cloth around the capacitors shall

not burn with a flame.

No electrical measurements are required.
