What is IP rating?

The IP rating/code is an abbreviation for Ingress Protection Rating or International Protection Rating. The code classifies the degree of protection for electrical enclosures and expresses the ability of enclosures to resist firm particles/solids (dirt, dust, and the like) as well as liquids like water/other fluid.

Electrical enclosures are rated with different IP ratings/codes; a code which consist of the letters IP followed by two digits. Each code represents the degree of protection from solids and liquids. The first digit in the code (e.g. IP65) reflects the protection degree from solids, while the second digit e.g. (IP65) reflects the protection degree from liquids (waterproof rating).

IP rating chart

The below chats explains the meaning behind the IP code and digits.

FIRST DIGIT

First digit

Protection of the enclosure from firm particles (solids)

IP0*

No protection

IP1*

Protection from solids greater than 50 mm in diameter

IP2*

Protection from solids greater than 12.5 mm in diameter

IP3*

Protection from solids greater than 2.5 mm in diameter

IP4*

Protection from solids greater than 1 mm

IP5*

Protection from dust

IP6*

Totally dust-proof

The first digit reflects the enclosure’s level of protection from firm particles/solids.

SECOND DIGIT (FLUID)

The second digit reflects the protection degree of the enclosure from harmful liquid ingress such as water/other fluid.

IP*

Second digit

Protection from  liquid ingress (waterproof rating)

Elaboration

IP*0

No protection

IP*1

Protection from vertically falling drops

Vertical drops should have no harmful effect

IP*2

Protection from vertically falling drops by an incline of up to 15 degrees

Vertical falling drops should not have any harmful effect when the equipment has an incline angle of up to 15 degress compared to the vertical line

IP*3

Protection from shower/rain

Shower/rain should have no harmful effect when the equipment has an incline angle of up to 60 degrees compared to the vertical line

IP*4

Protection from strong water splashes from all sides

Strong water splashes should have no harmful effect (strong shower/rain)

IP*5

Protection from rinsing from all sides

Rinsing (from tubes/nozzles) should not have any harmful effect

IP*6

Protection from strong rinsing from all sides

Strong rinsing from all sides should not have any harmful effect

IP*7

Protection from short term water immersion

No harmful effect should not be possible by short term immersion in water (from 15 cm up to 100 cm for at least 30 minutes)

IP*8

Protection from long term immersion

No harmful effect by lasting immersion in water under conditions specified with regards to arrangement between client and manufacturer of the enclosure

IP*9K

Protection from close-range high pressure, high temperature spray downs.

 

Blue Line is an expert in IP rated products for demanding environments.  This can be industrial PCs and monitors for dusty and wet environments.

Typically, our solutions are rated according to IP codes/protection classes IP65, IP66, IP67 and IP69K.

  • IP65: Totally dust-proof and protected from rinsing from all sides
  • IP66: Totally dust-proof and protected from strong rinsing from all sides
  • IP67: Totally dust-proof and protected from short term water immersion
  • IP69K: Totally dust-proof and protected from steam-jet cleaning

Products with IP69K classification are used in environments with tough cleaning e.g. within production of food and beverages.
