1 Test Conditions

Install each test sample in the same state as when it is mounted on an actual vehicle approximately 400 mm from a water discharge pipe that is equipped with a spray nozzle. The test samples shall be connected to the connectors and wiring harnesses. Spray water in accordance with the conditions shown in Table 23 while rotating the water discharge pipe around the XX-axis at a rate of approximately 23 revolutions per minute. Furthermore, the test samples shall be rotated around their vertical axis at a rate of approximately 17 revolution per minute.

If there is any difficulty in rotating the test samples with the wiring harness connected, or there is any possibility of interfering with the tester, it may be omitted to rotate the test samples.

1.2Nozzle diameter: 10mm, water temperature: normal temperature, water pressure: 10kPa, water volume: 1.9L/min, time: 10 minutes.

1.3Install the sample approximately 400mm away from a water discharge pipe that is equipped with a spray nozzle.
