Impact Protection

 

The IK Rating or Impact Protection Rating is an international classification of degrees of protection obtained by enclosures for electrical equipment against outer mechanical impacts.

It acts as a measure of quantifying the extent an enclosure has to protect its contents from external impacts adhering to IEC60068-2-75:1997 and IEC62262:2002.

IK00 - No Protection

IK01 - Protected against 0.14 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 56mm above the impacted surface)

IK02 - Protected against 0.2 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 80mm above the impacted surface)

IK03 - Protected against 0.35 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 140mm above the impacted surface)

IK04 - Protected against 0.5 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 200mm above the impacted surface)

IK05 - Protected against 0.7 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 280mm above the impacted surface)

IK06 - Protected against 1 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 400mm above the impacted surface)

IK07 - Protected against 2 joules of impact (the equivalent to the impact of a 0.5kg mass dropped from 400mm above the impacted surface)

IK08 - Protected against 5 joules of impact (the equivalent to the impact of a 1.7kg mass dropped from 300mm above the impacted surface)

IK09 - Protected against 10 joules of impact (the equivalent to the impact of a 5kg mass dropped from 200mm above the impacted surface)

IK10 - Protected against 20 joules of impact (the equivalent to the impact of a 5kg mass dropped from 400mm above the impacted surface)
