IP waterproof level testing equipment and testing standards are the concerns of many manufacturers. At present, both testing equipment and testing standards have relatively advanced indicators, which can already solve the standard problems of products for manufacturers, especially in the field of waterproofing.
IP waterproof test standard - IPX waterproof level standard (0-8 level)
The international industrial waterproof grade standard IPX and the Japanese industrial waterproof standard JIS grade are the same, divided into 9 grades from 0 to 8, which are recorded here.

Class 1 Can eliminate the harmful effects of vertically falling water droplets
Class 2 Protects against water droplets falling within 15 degrees from the vertical
Class 3 can eliminate the harmful effects of spray-like water droplets at 60 degrees from vertical
Level 4 can eliminate the harmful effects of water droplets splashing from different directions
Class 5 can eliminate harmful effects on water jets from nozzles in all directions
Level 6 can eliminate the harmful effects of strong water jets from nozzles in all directions
Level 7: The top is 0.15-1 meter away from the water surface for 30 minutes, the performance is not affected, and there is no water leakage
Level 8: The top is 1.5-30 meters away from the water surface for 30 minutes, the performance is not affected, and there is no water leakage
