The waterproof performance test of the lighting electrical ready board shall be conducted in accordance with the national standard GB/T 4208-2017 "Degrees of Protection Provided by Enclosures (IP Code)" or the international standard IEC 60529, and its protective ability shall be verified by simulating different environmental conditions. The following are common testing methods:

1. Water spray test (IPX5/IPX6)

IPX5： Use a nozzle with an inner diameter of 6.3mm to spray water continuously at a flow rate of 12.5L/min for at least 3 minutes at a distance of 2.5-3 meters from the electrical ready board, and check for any water droplets entering the live parts.

IPX6： Use a nozzle with an inner diameter of 12.5mm to spray water at a flow rate of 100L/min for at least 3 minutes at the same distance, under more stringent testing conditions.

2. Immersion test (IPX7)

Fully immerse the electrical ready board in water, with the water surface covering the top of the sample by at least 0.15 meters and the bottom at least 1 meter from the water surface, for 30 minutes to verify its sealing.

3. Rain test (IPX3/IPX4)

IPX3： Using a swinging tube device, spray water at a flow rate of 0.07L/min within a 60 ° range for 10 minutes.

IPX4： Expand the spray range to 180 ° to simulate a larger angle splashing environment.

4. Equipment and operation requirements

Experimental equipment: Standard water spray devices, immersion tanks, swing tube rain test chambers, etc. must be used.

Sample preparation: The sample should be a complete electrical ready board, including all accessories and seals, clean and free of dirt, and in normal working condition.

Result judgment: After the test, open the lid and check. If the water droplets do not enter the live parts and do not affect the normal use of the product, the judgment is passed.

5. Adaptation to special environments

For outdoor unobstructed electrical ready boards, they usually need to reach IP65/IP66 levels; The environment with obstruction can be relaxed to IP54/IP55; Indoor environments typically require IP21/IP33.

Through the above tests, it can be ensured that the lighting electrical ready board operates stably in humid, rainy and other environments, ensuring electrical safety.
