The needle flame test method adopts a standard butane needle flame to simulate tiny open flames generated by short circuits and burn specimens. It can only evaluate the ability of materials to resist instantaneous flame impact, and cannot restore the fire risks caused by long-term overload and continuous thermal conduction of motor windings and power resistors. Inside low-voltage electrical appliances, power batteries and heating household appliances, continuous heat generation of resistance coils and slow heat penetration into insulating parts are frequent fire triggers. The corresponding testing method is hot wire ignition test, which requires a dedicated Hot Wire Ignition Tester to carry out standardized tests.
