The capacitor is exposed to a flame for 15 seconds and then

removed for 15 seconds. This test is repeated for 5 cycles.

Active Flammability

The cheesecloth should not ignite.

The capacitors are individually wrapped in at least one, but not

more than two, complete layers of cheesecloth. They are then

subjected to 20 discharges. The interval between successive

discharges is 5 seconds. The VAC is maintained for 2 minutes

after the last discharge.

Passive Flammability

The burning time should not exceed

30 seconds.

The tissue paper should not ignite.

The capacitor under test is held into a flame and in a position

which best promotes burning. Each specimen is exposed to the

flame once.
