Introduction:

The enclosure shall be subjected to a spray of atomized water using a nozzle which produces a round pattern 75 to 100mm (3 to 4 in) in diameter when measured 300 mm (12 in) from the nozzle.The air pressure shall be 200 KPa(30 psi). Not less than 4.8 mL/linear cm (5 oz/linear ft) shall beapplied at a rate of 11.4 L/hour (3 gal/hour).
