IP (Ingress Protection) rating chart and what it means？
In our daily life, lots of items around us are indicated with different IP degree. Lots of us wondering, what is mean? If the product label marked as IP67, what is 6 stand for? What is 5 stand for?
|“Ingress Protection”||First Digit: Solids Protection||Second Digit: Liquids Protection|
|IP6, First Digit: the level of protection against solid foreign objects|
|IPX7, Second Digit: the level of protection against harmful ingress of water.|
According to international standard IEC 60529, IP Code ( also known as International Protection Rating, Ingress Protection Rating) classifies the degrees of protection provided against the intrusion of solid objects and liquid objects.
If a product marked as IP67, from the first numeric no.6, we know the product is dust protected. Then according to second numeric no. 7, that means the product is protected from water immersion up to 1m.
Below is the exact meaning for the first digit:
|Level||Object size protected against||Effective against|
|0||Not protected||No protection against contact and ingress of objects|
|1||>50mm||Any large surface of the body, such as the back of the hand, but no protection against deliberate contact with a body part.|
|2||>12.5mm||Fingers or similar objects.|
|3||>2.5mm||Tools, thick wires, etc.|
|4||>1mm||Most wires, screws, etc.|
|5||Dust Protected||Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact.|
|6||Dust Tight||No ingress of dust; complete protection against contact.|
