The IP rating for dust and water resistance

The water and dirt resistance of an AED is given in the IP classification. Every AED has an "IP Code" which stands for "International Protection Rating" or "Ingress Protection Rating.

The IP resistance grade is indicated with 2 digits: the first digit indicates protection against foreign objects and dirt, the second digit indicates resistance to water. The code is expressed as IPXX with "X" being numbers. For example, you may find an AED on the AEDexpert website that has an "IP" Rating of 55 (This is the second highest rating). The first numerical digit indicates the level of protection against solid particles such as dust, dirt or other matter. The second numerical digit indicates the level of protection from harmful ingress of water.

The higher the value of each number the higher the resistance to these contaminants. Here's the scale you can refer to as you compare AED models:

First Digit Description IP rate
0 No protection against contact and ingress of objects IP0X
1 Any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part IP1X
2 Fingers or similar objects IP2X
3 Tools, thick wires, etc IP3X
4 Most wires, screws, etc IP4X
5 Dust-proof - Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment IP5X
6 Dust-tight; complete protection against contact IP6X


The second numerical digit indicates the level of protection from harmful ingress of water:

Second Digit Description IP rate
0 Not protected IPX0
1 Dripping water IPX1
2 Dripping water when tilted up to 15 degrees IPX2
3 Spraying water IPX3
4 Splashing water IPX4
5 Water jets IPX5
6 Powerful water jets IPX6
7 Protected against submersion Up to 1 meter and for 30 minutes IPX7
8 Protected against laying under water IPX8


The most suitable AED for your situation depends on the needed IP rating. See our offer of AEDs with high IP ratings - average IP ratings and low IP ratings.
