请教61347-2-7的22.2 的高温测试,这里的高温是指应急驱动模块的最高ta 吗?谢谢。22.2 High temperature operation – The test of 22.1 is repeated at 0,9 times the rated
operating voltage but at the maximum of the declared ambient temperature range.
Normal lighting supply failure shall then be simulated and the battery shall operate the lamp
from the controlgear for the rated duration of the operation. At the end of the rated duration,
the measured battery voltage shall be at least Vmin as specified in Clause 20.
During the test, all parts, including batteries and lamps, shall be placed within the test
cabinet. Where the ambient temperature rating limit of the test battery is different from that
declared for the controlgear, then the battery should be held separately at its own maximum
declared temperature rating.
Compliance shall be checked by measurement.
