The IK rating is an international standard that indicates how resistant a product is to impact. The European standard EN 62262 relates to IK ratings, to identify the degree of protection provided by enclosures for electrical equipment against external mechanical impacts.
Strength as standard
Our experience has taught us that IK10 rating is inadequate against the sort of vandalism our products face on a regular basis. By testing to the EN60068-2-75 standard using a drop hammer (most lower IK tests use a pendulum hammer), we have extrapolated the data from the 20 joules (IK10) all the way up to 250 joules of energy (IK20).
Pendulum Hammer Test EN 60068-2-75 : 2014
|1.7 kg||300mm||5 Joules||IK 08|
|5 kg||200mm||10 Joules||IK 09|
|5 kg||400mm||20 Joules||IK 10|
Please note that EN 60068-2-75 does not allocate codes above IK10. The following codes are extrapolated and assigned IK references by Designplan Lighting.
|10 kg||350mm||35 Joules||IK 11|
|10 kg||500mm||50 Joules||IK 12|
|10 kg||750mm||75 Joules||IK 13|
|10 kg||1000mm||100 Joules||IK 14|
|10 kg||1250mm||125 Joules||IK 15|
|10 kg||1500mm||150 Joules||IK 16|
|10 kg||1750mm||175 Joules||IK 17|
|10 kg||2000mm||200 Joules||IK 18|
|10 kg||2250mm||225 Joules||IK 19|
|10 kg||2500mm||250 Joules||IK 20|
The video below demonstrates how we use a drop test to test our luminaires for impact.
Impact resistance goes hand-in-hand with ingress protection to ensure a luminaire can be installed in challenging environments such as an exposed coastal location for example. To find out more click on the link below.
