Annex E 67 Figure 1 Phase A Preheating 3.7.2. Phase B Direct exposure to flame (Figure 2) The tested-device shall be exposed to the flame from the freely burning fuel for 70 seconds. Figure 2 Phase B Direct exposure to flame 3.7.3. Phase C Indirect exposure to flame (Figure 3) As soon as phase B has been completed, the screen shall be placed between the burning pan and the tested-device. The tested-device shall be exposed to this reduced flame fora further 60 seconds. Instead of conducting phase C of the test, phase B may at the manufacturer’s discretion be continued for an additional 60 seconds. However this shall only be permitted where it is demonstrable to the satisfaction of the Test Agency that it will not result in a reduction in the severity of the test. Figure 3
