Ingress Protection Rating (IP Rating)

The IP rating system. Explained.


IP Rating

The IP Code, otherwise known as Ingress Protection Rating, or International Protection Rating, consists of the letters IP followed by two digits and an optional letter. As defined in the international standard IEC 60529, it classifies the degrees of protection provided against the intrustion of solid objects – for example, dust or water – in electrical enclosures. This standard aims to provide users more detailed information regarding the suitablity of an electrical product for use in various environments or locations.

The digits indicate conformity with the conditions, sumarrised below.

First Digit – Solids

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


Level of Protection

0No protection
1Protected against any solid object greater than 50mm in size, such as the back of a hand
2Protected against any solid object greater than 12.5mm in size, such as a finger
3Protected against any solid object greater than 2.5mm in size, such as a thick wire or a tool
4Protected against any solid object greater than 1mm in size, such as a wire or thin metal object
5Limited ingress of dust permitted
6Completely protected against dust

Second Digit – Liquids

The second digit indicates the level or protection that an enclosure provides against the harmful ingress of water or liquids in electrical equipment.


Level of Protection

0No protection
1Protected against vertical dripping water drops such as condensation
2Protected against dripping water drops at 15° angle from the vertical
3Protected against water spray up to a 60° angle from the vertical
4Protected against any water spray or spashes from any direction
5Protected against water jets from any direction
6Protected against powerful water jets from any direction
7Protected against immersion in water up to 1m for a maximum of 30 mins
8Protected against immersion in water for long periods
9Complete protection from high pressure water from any direction

What Level of Protection Do I Need?

The IP rating required varies depending on the demand of your application. If you’re looking to light an office, or shop where there is no change of condensation, the demands may be suitable for a unit with an IP rating of IP20. Alternatively, if you’re working in a hazardous environment, you’ll probably be requiring a unit that meets the demands of a fully IP68 rated unit.
