The IPX-4 level is basically the same as IPX-3, but it can provide all-around and angular splash water protection.
IPX-5 all-around and angle waterproof protection, providing 12.5 liters/sec flow rate for 2-3 minutes and 30n/m pressure waterproof protection.
IPX-6 big wave waterproof protection can last for 2 to 3 minutes to resist a depth of 3 meters underwater, a flow rate of 100 liters/minute, and a pressure of 100 n/m.
