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 | Test Type | Impact Energy | Class |
| 1,75 kg | 300mm | Pendulum or drop | 5 Joules | IK 08 |
| 5 kg | 200 mm | Pendulum or drop | 10 Joules | IK 09 |
| 5 kg | 400 mm | Pendulum or drop | 20 Joules | IK 10 |
| 10 kg | 500 mm | Pendulum or drop | 50 Joules | 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 | Test Type | Impact Energy | Class |
| 10 kg | 625 mm | Drop | 62.5 Joules | IK 12 |
| 10 kg | 750 mm | Drop | 75 Joules | IK 13 |
| 10 kg | 1000 mm | Drop | 100 Joules | IK 14 |
| 10 kg | 1250 mm | Drop | 125 Joules | IK 15 |
| 10 kg | 1500 mm | Drop | 150 Joules | IK 16 |
| 10 kg | 1750 mm | Drop | 175 Joules | IK 17 |
| 10 kg | 2000 mm | Drop | 200 Joules | IK 18 |
| 10 kg | 2250 mm | Drop | 225 Joules | IK 19 |
| 10 kg | 2500 mm | Drop | 250 Joules | IK 20 |
