5.7.1 Test Method

The enclosure and its external mechanisms shall be subjected to a stream of water from a hose that has a 25mm(1 in) inside diameter nozzle that delivers at least 240L(65 gal) per minute.

The nozzle shall be held from 3.0 to 3.5m(10 to 12 feet)from the enclosure,and the spray of water shall be directed at all points of potential water entry such as seams,joints,external operating mechanisms,and such.A seam is the junction of,or the joint between,two pieces.When two covers or doors are adjacent,their common edges shall be considered a single seam.The nozzle shall be moved along each test point one time at a uniform nominal rate of 6mm/sec.

A conduit shall be permitted to be installed to equalize internal and external pressures but shall not serve as a drain.

5.7.2 Evaluation

The enclosure shall be considered to have met the requirements if at the conclusion of the test no water has entered the enclosure.
