IEC 60950-1:2013 Annex A.3 Hot Flaming Oil Test Apparatus – BONAD Flammability Test Chamber
Test Principle:
The test procedure involves placing 10mL of a specified flammable liquid (with an average calorific value of 38MJ/L, a unit volume mass between 0.845g/mL and 0.865g/mL, and a flash point ranging from 43.5℃ to 93.5℃) into a metal spoon. This liquid is then heated to the ignition point of distillate fuel oil and burned for one minute. The spoon is rotated at a specific height (100mm) and flow rate (1mL/s) by a motor, which steadily pours the flammable liquid into the center of the sample’s opening (fireproof enclosure structure). The fireproof performance of the test product is evaluated based on whether an ignition cushion layer with a specified distance (50mm) and density (40g/m²) beneath the test product catches fire.
