International Protection Rating Code (IP Code)

The IP Code classifies and rates the degrees of protection against the instruction of solid objects. (including body parts like hands and fingers), dust, accidental contact, and water in mechanical casings and with electrical enclosures.

The IP Code is rated by the two numbers based on the following chart.

1st Digit Solid Object Protection 2nd Digit Water Protection

0

No protection againts contact and ingress of objects

0

Not Protected

1

Objext size protection: Greater than 1.97 inches (50mms)

1

Dripping Water (Vertically falling drops) shall have no harmful effects

2

Objext size protection: Greater than 0.49 inches (12.5mm)

2

Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position.

3

Objext size protection: Greater than 0.1 inches (2.5mm)

3

Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect.

4

Objext size protection: Greater than 0.04 inches (1mm)

4

Water splashing against the enclosure from any direction shall have no harmful effect.

5

Objext size protection: Dust Protected

5

Water projected by a nozzle 0.25 inches(6.3mm) against enclosure from any direction shall have no harmful effects.

6

Objext size protection: Dust tight

6

Water projected in powerful jets nozzle 0.5 inches (12.5mm ) against the enclosure from any direction shall have no harmful effects.

7

Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).

~

8

The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects.

Examples:

  • IP65 Dust proof, protected from splashes and low-pressure jets
  • IP66 Dust proof, protected from strong water jets
  • IP67 Dust proof, protected from temporary immersion in water 3.3' deep for 30 minutes
  • IP68 Dust proof, protected from continuous immersion in water under more severe conditions than IP67
