IP Code

The IP Code (or Ingress Protection Rating, sometimes also interpreted as InternationalProtection Rating) consists of the letters IP followed bytwo digits or one digit and one letter and an optional letter. As defined in internationalstandard IEC 60529, IPCode classifies and rates the degrees of protection provided against theintrusion of solid objects (including body parts like hands and fingers), dust,accidental contact, and water in mechanical casings and withelectrical enclosures.

The standard aims to provide users more detailed information than vaguemarketing terms such as waterproof. However,no edition of the standard is openly published for unlicensed readers.

The digits (characteristic numerals) indicate conformity with theconditions summarized in the tables below. Where there is no protection ratingwith regard to one of the criteria, the digit is replaced with the letter X.

For example, an electrical socket rated IP22 is protected againstinsertion of fingers and will not be damaged or become unsafe during aspecified test in which it is exposed to vertically or nearly verticallydripping water. IP22 or 2X are typical minimum requirements for the design ofelectrical accessories for indoor use.

Solid particle protection

The first digit indicates the level of protection that the enclosureprovides against access to hazardous parts (e.g., electrical conductors, movingparts) 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

Protection of the equipment inside the enclosure against harmful ingressof water.

Not protected

1

Dripping water

Dripping water (vertically falling drops) shall have no harmful  effect.

Test duration: 10 minutes

Water equivalent to 1mm 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 3mm rainfall per minute

3

Spraying water

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

Test duration: 5 minutes

Water volume: 0.7 litres per minute
 Pressure: 80
–100
kN/m²

4

Splashing water

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

Test duration: 5 minutes

Water volume: 10 litres per minute
 Pressure: 80
–100
kN/m²

5

Water jets

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

Test duration: at least 3 minutes

Water volume: 12.5 litres per minute
 Pressure: 30
kN/m² at distance of 3m

6

Powerful water jets

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

Test duration: at least 3 minutes

Water volume: 100 litres per minute
 Pressure: 100
kN/m² at distance of 3m

7

Immersion up to 1 m

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 minutes

Immersion at depth of 1m

8

Immersion beyond 1 m

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 water

Depth specified by manufacturer
