What does Impact Protection(IK) Rating Mean?
The IK rating means the degrees of protection provided by enclosures for electrical equipment against external mechanical impacts or shocks in joules. The IK rating consists of two digits (00 to 10) after the term ‘IK’ (e.g. IK05).
IK ratings are particularly important for security equipment that may be fitted in an area that could be subject to rough environment attempted vandalism or other impacts. These ratings are also useful for other electrical equipment such as switches or keyboards.
IK ratings are an international numeric classification specified in accordance with IEC 62262:2002 and IEC 60068-2-75:1997.
| IK Rating | Impact Energy (In Joules) |
|---|---|
| IK00 | no shock resistance |
| IK01 | 0.14 (hit with hand or fist) |
| IK02 | 0.20 (hit with hand or fist) |
| IK03 | 0.35 (hit with hand or fist) |
| IK04 | 0.50 (hit with hand or fist) |
| IK05 | 0.70 (hit with hand or fist) |
| IK06 | 1.0 (500 g fall from 20 cm) |
| IK07 | 2.0 (500 g fall from 40 cm) |
| IK08 | 5.0 (1.7 kg fall from 29.5 cm) |
| IK09 | 10.0 (5 kg fall from 20 cm) |
| IK10 | 20.0 (5 kg fall from 40 cm) |
IK00 – No Protection against shock
IK01 – Protected against 0.14 joules of impact. The equivalent to the impact of a 0.25kg mass dropped from 5.6 cm above the impacted surface.
IK02 – Protected against 0.2 joules of impact. The equivalent to the impact of a 0.25kg mass dropped from 8 cm above the impacted surface.
IK03 – Protected against 0.35 joules of impact. The equivalent to the impact of a 0.2kg mass dropped from 14 cm above the impacted surface.
IK04 – Protected against 0.5 joules of impact. The equivalent to the impact of a 0.25kg mass dropped from 20 cm above the impacted surface.
IK05 – Protected against 0.7 joules of impact. The equivalent to the impact of a 0.25kg mass dropped from 28 cm above the impacted surface.
IK06 – Protected against 1 joule of impact. The equivalent to the impact of a 0.5kg mass dropped from 20 cm above the impacted surface.
IK07 – Protected against 2 joules of impact. The equivalent to the impact of a 0.5kg mass dropped from 40 cm above the impacted surface.
IK08 – Protected against 5 joules of impact. The equivalent to the impact of a 1.7kg mass dropped from 29.5 cm above the impacted surface.
IK09 – Protected against 10 joules of impact. The equivalent to the impact of a 5kg mass dropped from 20 cm above the impacted surface.
IK10 – Protected against 20 joules of impact. The equivalent to the impact of a 5kg mass dropped from 40 cm above the impacted surface.
