Ingress Protection
First Digit: Solid Protection
Second Digit: Liquids Protection

The Ingress Protection (IP) code (or International Protection Rating, also interpreted as Ingress Protection Rating) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, classifies and rates the degree of protection provided against intrusion (body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The equivalent standard is EN 60529. The standard aims to provide users with more detailed information than vague marketing terms such as “waterproof”.

The digit (characteristic numerals) indicate conformity with the conditions summarized in the table below. For example, if an object is rated IP00 indicates that it is not protected against contact and ingress of objects and no protection against any form of liquids. Another example, an electrical socket rated IP62 has complete protection against contact and will not be damaged or become unsafe during a specified test where it is exposed to vertically dripping water.

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

Level
Object size
protected against
Effective against
0
Not protected
No protection against contact and ingress of objects
1
>50mm
Any large surface of the body, such as the back of the hand,
but no protection against deliberate contact with a body part.
2
>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 satifactory operation of the equipment; complete protection against contact.
6
Dust Tight
No ingress of dust; complete protection against contact.

Second Digit: Liquids
Protection of the equipment inside the enclosure against harmful ingress of water.

1
Dripping Water
Dripping water (vertically falling drops) shall have no harmful effects.
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.
3
Spraying Water
Water falling as a spray at any angle up to 60°
from the vertical shall have no harmful effect.
4
Splashing Water
Water splashing against the enclosure from any direction 
shall have no harmful effect.
5
Water Jets
Water projected by a nozzle (6.3mm) against enclosure 
from any direction shall have no harmful effects.
6
Powerful Water Jets
Water projected in powerful jets (12.5mm nozzle) against 
the enclosure from any direction shall have no harmful effects.
7
Immersion up to 1m
Ingress of water in harmful quality shall not be possible 
when the enclosure is immersed in water under defined 
conditions of pressure and time (up to 1m of submersion).
8
Immersion beyond 1m
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.
