The “IK” rating or code is an international standard which standardises and defines the level of resistance of enclosures provided for electronic equipment to mechanical impacts and this rating can be an important factor when choosing an outdoor camera or webcam which may be fitted in an area which could be subject to attempted vandalism or other impact. To check on equipments protection against the ingress of dust or moisture you should also check the equipments IP rating too.
IK Protection Explained
The degree of mechanical protection is identified by a code that consists of the letters IK followed by two digits.
| IK number | Energy | Equivalent impact |
|---|---|---|
| 00 | Non-protected | No test |
| 01 | Impact energy: 0,150 joules | Resistant against an impact from an object of 200 grams from a distance of 5,6 cm |
| 02 | Impact energy: 0,200 joules | Resistant against an impact from an object of 200 grams from a distance of 8,0 cm |
| 03 | Impact energy: 0,350 joules | Resistant against an impact from an object of 200 grams from a distance of 14,0 cm |
| 04 | Impact energy: 0,500 joules | Resistant against an impact from an object of 200 grams from a distance of 20 cm |
| 05 | Impact energy: 0,700 joules | Resistant against an impact from an object of 200 grams from a distance of 28 cm |
| 06 | Impact energy: 1,00 joules | Resistant against an impact from an object of 500 grams from a distance of 20 cm |
| 07 | Impact energy: 2,00 joules | Resistant against an impact from an object of 500 grams from a distance of 40 cm |
| 08 | Impact energy: 5,00 joules | Resistant against an impact from an object of 1.7 kg from a distance of 30 cm |
| 09 | Impact energy: 10,00 joules | Resistant against an impact from an object of 5 kg from a distance of 20 cm |
| 10 | Impact energy: 20,00 joules | Resistant against an impact from an object of 5 kg from a distance of 40 cm |
