19、in. If atthe end of 5 min the current is stable or dropping and has notexceeded 100 A at any time during the test, or flashed over,the specimen has passed the test. If at the end of 5 min thecurrent is rising and not stable but does not exceed 100 A, orflashover, the test shall continue for an addit

20、ional 25 min.
