Specification
Test Method
The capacitor under test is held into a flame and in a position
which best promotes burning. Each specimen is exposed to the
flame one time.
Test Specimen
Passive Flammability
The burning time should not exceed 30
seconds.
The tissue paper should not ignite.

Pre-treatment: Capacitor shall be stored at 85±2 for 1 hour then
placed at room condition¹ for 24±2 hours.
Post-treatment: Capacitor is stored for 1 to 2 hours at room
condition¹.
