IPX waterproof rating standard (0-8)
The international industrial waterproof grade standard IPX and the JIS grade of the Japanese industrial waterproof standard are consistent, and are divided into 9 grades of 0-8, which are recorded here.

Level 0 No Protection

Level 1 can eliminate the harmful effects of vertically falling water droplets
Level 2 has a protective effect on water droplets falling within 15 degrees from the vertical direction
Level 3 can eliminate the harmful effects of spray-like water droplets at 60 degrees with the vertical direction
Level 4 can eliminate the harmful effects of splashing water droplets from different directions
5 levels can eliminate the harmful effects of jet flow from nozzles in all directions
Level 6 can eliminate the harmful effects of strong jet water flow from nozzles in all directions
The top of level 7 is -1 meter away from the water surface for 30 minutes, the performance is not affected, and there is no water leakage
The top of level 8 is -30 meters away from the water surface, continuously for 60 minutes, the performance is not affected, and there is no water leakage
