IK02: Protected against 0,2 joules impact. Equivalent to impact of 0.25kg mass

dropped from 80 mm above impact- IP65 ed surface.

 

IK10: Protected against 20 joules impact. Equivalent to impact of 5kg mass dropped from 400 mm above impacted surface.

 

IP20: Luminaires which can be applied indoors only if no specific pollution rates are expected. Offices, dry, heated industrial halls, shops, shop- ping malls and theatres are typical application segments. Protected against a solid object greater than 12.5 mm such as a finger.

 

IP 44: Protected against a solid object greater than 1mm such as a wire. Protected against water splashed from all directions. Limited ingress permitted.

 

IP65: Jet-proof Iuminaires which are ap- plicable where the surroundings are hosed down frequently by water jets, or where luminaires are applied in a dusty environment. Although the lu- minaires are not fully watertight, the potential ingress of moisture will not have any harmful effect on the lumi- naire function. IP 65 luminaires are often available in impact-protected versions. Dust tight. No ingress of dust. Two to eight hours. Protected against jets of water. Limited ingress permitted.
