The other circuits shall not be energized. A recovery to initial conditions is required between two successive tests. This procedure shall be r

26、epeated eight times for each circuit. Temporary emission of smoke due to thermal degradation of surface contamination products is permissible. This shall not be considered as a defect if performance is not affected. 4.3 Final measurements (if applicable) The specimens shall be subjected to the follo
