IK Rating classifies the level of protection electrical appliances provide against mechanical impacts from outside. It is defined by the standard IEC 62262.The degree of mechanical protection is identified by a code that consists of the letters IK followed by two digits:
| Code | Impact energy (Joules) | Test |
| 00 | Non-protected | |
| 01 | 0.15 | Resistant against an impact from an object of 200 grams thrown from a distance of 7.5 cm |
| 02 | 0.2 | Resistant against an impact from an object of 200 grams thrown from a distance of 10 cm |
| 03 | 0.35 | Resistant against an impact from an object of 200 grams thrown from a distance of 17.5 cm |
| 04 | 0.5 | Resistant against an impact from an object of 200 grams thrown from a distance of 25 cm |
| 05 | 0.7 | Resistant against an impact from an object of 200 grams thrown from a distance of 35 cm |
| 06 | 1.0 | Resistant against an impact from an object of 500 grams thrown from a distance of 20 cm |
| 07 | 2.0 | Resistant against an impact from an object of 500 grams thrown from a distance of 40 cm |
| 08 | 5.0 | Resistant against an impact from an object of 1.7 kg thrown from a distance of 29.5 cm |
| 09 | 10.0 | Resistant against an impact from an object of 5 kg thrown from a distance of 20 cm |
| 10 | 20.0 | Resistant against an impact from an object of 5 kg thrown from a distance of 40 cm |
