stream of water from a hose which has a 1-inch nozzle and which delivers at-least 65 gallons per minute. The-water shall be directed at the enclosure
,j{} from all angles from a distance of 10 to 12 feet for a total period of 5 '
minutes. The conduit entrance will be sealed.
6.7.1.2 Evaluation The enclosure is considered watertight and dusttight if no water has entered the enclosure. .
