Step 1. Place item in its normal operating position, with patient cable and defibrillator paddles attached, on a platform or tilt table in a manner such that it can be oriented horizontally and in any of four directions forward, backward, and to each side to the extent of 15 degrees from the horizontal plane.

Step 2. Attach a spray nozzle with a uniformly distributed full cone spray pattern to a flexible hose and using a container calibrated in liters or an equivalent method, determine the rate of flow out of the nozzle. The requirements for water flow shall be 4.3 gallons per hour for each square foot of area covered by the spray 3 feet below the nozzle.

Step 3. Position the nozzle 3 feet above the item so that the spray is directed downward onto it. The item shall be subjected to a uniform spray over the entire surface being tested. During the test, the item shall not be operated, but all controls shall be immediately accessible to the operator: i.e., uncovered, with the exception of the recorder, which may be protected.

Step 4. Direct the spray onto the top of the item (with platform or tilt table horizontal) for at least eight minutes. Turn off spray four minutes.

Step 5. Direct the spray downward onto the item for at least eight minutes with the platform or table tilted such that the item is oriented 15 degrees from the horizontal in the forward position. Turn off spray four minutes.

Step 6. Direct the spray downward onto the item for at least eight minutes with the platform or table tilted such that the item is oriented 15 degrees from the horizontal in the backward position. Turn off spray four minutes.

Step 7. Direct the spray downward onto each remaining side of the Item for at least eight minutes with the platform or table tilted such that the side being sprayed is oriented 15 degrees from the vertical. Turn off spray for four minutes.

Step 8. Return the item to the horizontal and perform a satisfactory operation test.
