IK RATINGS

IK Ratings (otherwise known as Impact Protection Rating) became a specific rating to measure the impact resistance of a product in 1995. 


They consist of the letters IK, followed by two digits. These two digits help us to identify the level of protection a piece of electrical equipment offers by its resistance against external mechanical impacts by Kinetic energy. 


While EN 62262 specifies the way enclosures should be mounted when tests are carried out, the atmospheric conditions that should prevail, the number of impacts (5) and their (even) distribution, size, style, material, dimensions of the various types of hammer designed to produce the energy levels required.

The table below defines the IK codes and the impact protection tests that they withstand, based on the tests carried out according to IEC 62262

No Protection

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

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

Protected against 0.35 joules of impact (the equivalent to the impact of a 0.2kg mass dropped from 140mm above the impacted surface)

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

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

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

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

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

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

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