Hot Flaming Oil Flammability Test Chamber IEC 60950 Annex A.3
Products Description
IEC 60950-1:2013 Annex A.3 Hot Flaming Oil Test Apparatus
Product overview:
The hot flaming oil test device conforms to IEC60950-1:2005 and IEC60950-1:2013 clause 4.6.2, Annex A.3. It is used to simulate that the flammable liquids used in electrical and electronic equipment may ignite due to overheating and leak out of the fire protection enclosure, causing electrical fires and endangering the reliable operation of the equipment and personal safety.
Test principle:
Fill 10mL of flammable liquid with the specified performance (average calorific value 38MJ/L, mass per unit volume between: 0.845g/mL～0.865g/mL, flash point: 43.5℃~93.5℃) in the metal ladle, after heating to the distillate fuel oil’s ignition point and burning 1mim, the motor drives the spoon to rotate at a certain height (100mm) and a certain flow rate (1mL/s), and then steadily pour the flammable liquid on the center of the opening of the sample (fire protection enclosure). The fire protection performance of the test product is evaluated by whether the ignition bedding at the specified distance (50mm) and with the specified density (40g/m2) under the test product is ignited.
