主要特點(diǎn)：

The electrical burner test involves submitting, under defined conditions, the test piece to the action of a heat radiation and hot gases sweeping the surface of the test piece, thus enabling the progress and the propagation of the flame. A pilot flame produced by a batwing burner supplied with propane gas is applied at at times scheduled by the standard and is used to ignite the evolved gases and possibly cause the inflammation of the material.


For each test, the time to inflammation, the persistence of the flame, the nature and the effects of combustion are noted.
