IP Ratings and IP Rating Chart

Last Updated on November 26, 2023 by Electricalvolt

IP ratings classify the levels of protection against solid objects, dust, accidental contact, and water in electrical enclosures. IP ratings are key for understanding how well an instrument is sealed against dust and moisture.

What is IP Protection?

IP” stands for “ingress protection.” This is the degree to which the instrument can withstand the invasion of foreign matter.

The IP rating system was established by the IEC (International Electrotechnical Commission). It is the IEC standard 60529, used as a guide to help to protect the life of the instrument.

This can also help the engineer to make a more informed purchasing decision by ensuring that that piece of enclosure is designed to work in the environment the user faces.

IP” capability comprises two digits, each signifying a separate feature. The naming indicates how well the instrument is sealed against the invasion of foreign matter, both moisture and dust. The higher the IP number, the better the degree of protection.

What could a typical IP54 rating tell a buyer about a model’s application capabilities? If you want to sound completely knowledgeable, this is IP five-four, not fifty-four.

Note that each digit refers to a separate capacity, not each other.

The first digit mentions particle ingress, reflecting the degree to which solid objects can enter the box. A level “5” indicates “dust protected” as well as invasion protection with a wire below 1.0 mm.

The 1st digit ranges from 0 to 6, reflecting the degree of protection against solid particles.

The 2nd digit ranges from 0 to 9 and indicates the protection against the water ingress.

Meaning of the two digits in an IP Ratings

First Digit – Solid Protection Level.

The first digit in IP ratings indicates the enclosure’s level of protection against access to hazardous parts and ingress of solid objects.

Level
Object size protected against
Effective against
0No protectionNo protection against contact and ingress of objects
1ip-ratings-solid-object-50mm
>50mm
Any large surface of the body, such as the back of the hand, but no protection against deliberate contact with a body part.
2ip-ratings-solid-objects-12.5mm

>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.

Second digit – Water protection level.

The second digit in IP ratings shows the degree of protection of the equipment inside the enclosure against water ingress.

Level
Object size protected against
Effective against
0
Not Protected
1dripping-water-ip-protection
Dripping water
Vertical drops of dripping water shall not cause any harmful effects.
2dripping-water-vertically falling-drops-ip-protection

Dripping water (vertically falling drops) shall have no harmfull effect.
When the enclosure is tilted up to 15°, vertically dripping water will not cause harm.
3protected-against-spray-of water

Spraying water
Water spray up to 60° from vertical has no harmful effect.
4splashing-water-protection
Splashing water
Water splashing onto the enclosure from any angle should not cause any damage or harm.
5jet-of-water-protection
Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects.
Water projected by a nozzle of 6.3mm against an enclosure from any direction shall not cause harm.
6powerful-water-jet-protection
Powerful water jets
Water projected in powerful jets (12.5mm nozzle) from any direction shall not harm the enclosure.
7water-projected-in-harmful-jets

Immersion up to 1m
Ingress of water shall not be possible when the enclosure is submerged to a depth of 1 meter under specified pressure and time.
8protected-against-immersion-in-water

Immersion beyond 1m
The manufacturer specifies the conditions under which the equipment can be continuously immersed in water. Usually, this means the equipment is tightly sealed. However, in some cases, the equipment may allow water to enter, but in a way that does not cause any harm.
