IK Rating

Degree of impact Protection EN62262.

IK rating system is an international classification showing degrees of protection provided by luminaires against external mechanical impacts.

Number Measure of Protection - Impact energy (joules) Test
IK/00 No protection to this standard
IK/01 0.15 0.20 kg impact
IK/02 0.20 0.20 kg impact
IK/03 0.35 0.20 kg impact
IK/04 0.50 0.20 kg impact
IK/05 0.70 0.20 kg impact
IK/06 1.00 0.50 kg impact
IK/07 2.00 0.50 kg impact
IK/08 5.00 1.70 kg impact
IK/09 10.00 5.00 kg impact
IK/10 20.00 5.00 kg impact

 

When higher impact energy protection is required 50 joules is recommended.
