What is an IP Rating?

blankThe IP Rating (or Ingress Protection Rating) classifies and rates the degrees of protection against the intrusion of solid objects, dust, accidental contact, water in mechanical casings and with electrical enclosures.

The code will start out with IP followed by two digits. The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (electrical conductors, moving parts etc.) and the ingress of solid foreign objects. The second digit defines the protection of the equipment inside the enclosure against various forms of moisture (drips, sprays, submersion etc.) The higher each of the numbers in an AED’s IP rating, the more protected it is. AEDs with higher IP ratings are recommended for professional rescuers and devices that will be housed outside or near water, such as a pool or marina. Those with lower IP ratings should be used in controlled environments such as schools, homes, or offices.

AEDs are tested on the following scales:

Solid Particle Protection

0          No protection against contact and ingress of objects.

1          Any large surface of the body, such as the back of the hand, but no protection against deliberate contact with a body part.

2          Fingers or similar objects.

3          Tools, thick wires, etc.

4          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.

6          Dust tight. No ingress of dust; complete protection against contact.

Liquid Ingress Protection

0          Not protected

1          Dripping water

2          Dripping water when tilted up to 15 degrees

3          Spraying water

4          Splashing water

5          Water jets

6          Powerful water jets

7          Immersion up to 1 meter

8          Immersion beyond 1 meter
