The standard IPX of the international industrial production waterproof level is the same as the JIS level of the American manufacturing groundwater level waterproof standard, divided into 9 levels 0-8, and recorded here.
Level 0 unprotected;
Level 1 also eliminates the harmful effects of vertically falling water droplets;
Level 2: It has the safety protection function of reducing water droplets within 15 degrees from the vertical angle;
Level 3 also eliminates the harmful effects of water spray droplets at a vertical angle of 60 degrees;
Level 4 also eliminates the harmful effects of water droplets splashed from other directions;
Level 5 also eliminates the harmful consequences of the volume of water ejected from the nozzle in all directions;
Level 6 also eliminates the harmful and adverse effects of super-strong water discharge from nozzles in all directions;
The top of level 7 is 0.15-1 m from the water surface and lasts for 30 minutes.Service performance was unaffected and there were no water leaks.
The top of level 8 is 1.5-30m from the water surface and lasts for 30 minutes.Service performance was not adversely affected and there were no water leaks.
In the future, you should look out for three proofing phones to buy.Only people with levels 7 and 8 are really waterproof; level 6 can also be called rainproof.Cell phones and GPs used for outdoor activities should be at this level.
