IP Ratings Explained

The IP (Ingress Protection) Rating of a product consists of 2 numbers. The digit represents the products resistance to solids and the second to liquids. The IP Rating requirements of a product depends on the desired application, for example fittings in bathrooms may require a higher rating than other areas of a property.

Example IP Rating: IP65

First Digit: Protection from Solids

 

LevelObject size protected againstEffective against
0Not protectedN/A
1>50mmAny large surface of the body, such as the back of the hand, but no protection against deliberate contact with a body part.
2>12.5mmFingers or similar objects.
3>2.5mmTools, thick wires, etc.
4>1mmMost wires, screws, etc.
5Dust ProtectedIngress 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.
6Dust TightNo ingress of dust; complete protection against contact.

 

Second Digit: Protection from Liquids

1Dripping waterDripping water (vertically falling drops) shall have no harmful effect.
2Dripping 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.
3Spraying waterWater falling as a spray at any angle up to 60° from the vertical shall have no harmful effect.
4Splashing waterWater splashing against the enclosure from any direction shall have no harmful effect.
5Water jetsWater projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects.
6Powerful water jetsWater projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects.
7Immersion up to 1mIngress 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).
8Immersion beyond 1mThe 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.

 

For example, our D-lux LED Downlights are IP65. This means they are suitable for bathrooms with resistance to water jets, as well as being completely dust proof.
