The IK code is an international numeric classification for the degrees of protection provided by enclosures for electrical equipment against external mechanical impacts. It provides a means of specifying the capacity of an enclosure to protect its contents from external impacts. The IK Code is international standardized in IEC 62262 (relate to EN 62262, in the past EN 50102). There are ten protection types according to the impact energy which the enclosure can resist at least.

Definition of the protection types (level of impact protection)

00 = no protection

Test: - - - - -

01-05 = Impact < 1 Joule

Test: Impact from short distance

06 = Impact 1 Joule

Test: 500g from 20 cm

07 = Impact 2 Joule

Test: 500g from 40 cm

08 = Impact 5 Joule

Test: 1,7 kg from 29,5 cm

09 = Impact 10 Joule

Test: 5 kg from 20 cm

10 = Impact 20 Joule

Test: 5 kg from 40 cm
