Ingress Protection Levels

Ingress Protection Levels

Solid particle Ingress Protection

The first digit indicates the level of ingress protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.

Level

Object size protected against

Effective against

0

No protection against contact and ingress of objects

1

>50   mm Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part

2

>12.5   mm Fingers or similar objects

3

>2.5   mm Tools, thick wires, etc.

4

>1   mm 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

 

Liquid Ingress Protection

The second digit indicates the level of ingress protection that the enclosure provides against harmful ingress of water.

Not protected Not Necessary Not Necessary

1

Dripping water Dripping water (vertically falling drops) shall have no harmful effect. Test   duration: 10 minutesWater equivalent   to 1 mm rainfall per minute

2

Dripping water when tilted up to 15° Vertically dripping water shall have no harmful effect when the enclosure is tilted at   an angle up to 15° from its normal position. Test duration: 10 minutes. Water equivalent to 3 mm rainfall per minute

3

Spraying water Wate falling as a spray at any angle up to 60° from the vertical shall have no   harmful effect. Test   duration: 5 minutesWater   volume: 0.7 litres per minute Pressure: 80–100 kPa

4

Splashing water Watersplashing against the enclosure from any direction shall have no harmful effect. Test   duration: 5 minutesWater   volume: 10 litres per minute Pressure: 80–100 kPa

5

Water jets Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects. Test   duration: at least 3 minutesWater   volume: 12.5 litres per minute Pressure: 30 kPa at distance of 3 m

6

Powerful water jets Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects. Test   duration: at least 3 minutesWater   volume: 100 litres per minute Pressure: 100 kPa at distance of 3 m

7

Immersion up to one meter 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). Test   duration: 30 minutesImmersion   at depth of at least 1 m measured at bottom of device, and at least 15 cm   measured at top of device

8

Immersion beyond one meter 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. Test   duration: continuous immersion in waterDepth   specified by manufacturer

Additional Ingress Protection letters

The standard defines additional letters that can be appended to classify only the level of protection against access to hazardous parts by persons:

Level
