The IK rating is an international standard that indicates how resistant a product is to impact. The standard BS 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 the IK11 rating is inadequate against the sort of vandalism our products face on a regular basis. By testing to the BS EN60068-2-75 standard using a drop hammer we have extrapolated the data from 50 joules (IK11) all the way up to 250 joules of energy (IK20).
In 2021, IK 11 representing the impact energy value of 50 joules was added.
IK rating
Test BS EN 60068-2-75
| Weight | Height | Impact energy | Test type | Class |
| 1.7 kg | 300mm | 5 Joules | Pendulum or drop | IK 08 |
| 5 kg | 200mm | 10 Joules | Pendulum or drop | IK 09 |
| 5 kg | 400mm | 20 Joules | Pendulum or drop | IK 10 |
| 10 kg | 500mm | 50 Joules | Pendulum or drop | IK 11 |
Please note that BS EN 62262 does not allocate codes above IK11. The following codes are extrapolated and assigned IK references by Designplan Lighting.
| Weight | Height | Impact energy | Test type | Class |
| 10 kg | 625mm | 62.5 Joules | Drop | IK 12 |
| 10 kg | 750mm | 75 Joules | Drop | IK 13 |
| 10 kg | 1000mm | 100 Joules | Drop | IK 14 |
| 10 kg | 1250mm | 125 Joules | Drop | IK 15 |
| 10 kg | 1500mm | 150 Joules | Drop | IK 16 |
| 10 kg | 1750mm | 175 Joules | Drop | IK 17 |
| 10 kg | 2000mm | 200 Joules | Drop | IK 18 |
| 10 kg | 2250mm | 225 Joules | Drop | IK 19 |
| 10 kg | 2500mm | 250 Joules | Drop | IK 20 |

Ingress Protection
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.
