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. If atthe end of that time the rope has not flashed over and thecurrent has stabilized at less than 100 A, the specimen haspassed.11.4 Electrical Test Procedure-Wet Test:11.4.1 Specimen for TestWhen selected in accordancewith Section 8, the test specimen shall be at least 1.8 m (6 ft)lo
