Applicable standards: > IEC/EN 60529
IEC/EN60529 Waterproof is divided into 9 levels (level 0 ~ grade 8), waterproof grade (E.G. IPX4-
Waterproof level 4): Level 0 0 : Complete waterproof and non -protection
Level 1: The dripping of water in the vertical direction should have no harmful effect
Level 2: The vertical surface of the shell is 15 ° at 15 ° When tilted within the range, vertical dripping should have no harmful effect level 3: eachPermailing water in a vertical surface 60 °, no harmful effect Level 4: splashing water in all directions of the shell has no harmful effect
level 5: spray water in all directions of the shell, no harmful effects level 6: to the shell: to the shell:There is no harm of water spraying in all directions Level 7: The amount of water intake in the water that is immersed in the prescribed pressure is not harmful after the specified time
Level 8: According to the conditions agreed by the manufacturer and the user (should be compared with Level 7Strict) The amount of water inlet in the shell is not harmful after continuous diving
Level 9: High -pressure test
