WE EXPLAIN THE CONCEPTS

People are affected by how we plan our lighting. And the choice of products is affected by the type of environment being illuminated. In exposed environments that are damp, corrosive or extremely dusty, it is very important to possess a knowledge of different classifications and designations.

D-CLASSIFICATION — FOR AREAS WITH HEIGHTENED FIRE RISK

Luminaires that are installed in areas with heightened fire risk where there is a risk of dust collecting on the luminaire casing must be approved for use in such environments. A D-marking means that the luminaire has limitations when it comes to maximum surface temperature (maximum +90°C during normal operation).

IK CODE – IMPACT RESISTANCE

A luminaire’s resistance to external mechanical impact is classified using the international IK rating. The rating goes from IK00 to IK10, where IK00 has no particular protection against external impact. A luminaire rated with IK10, on the other hand, can withstand a direct impact of 20 Joules, which corresponds to a sphere weighing about 2 kg being dropped from a height of one metre.

IK	IK01	IK02	IK03	IK04	IK05	IK06	IK07	IK08	IK09	IK10
Joule	0,14 J	0,2 J	0,35 J	0,5 J	0,7 J	1 J	2 J	5 J	10 J	20 J

*A D-marked luminaire is not required if the environment is not dusty, special study required. For more detailed information, read “the Swedish electrical installations in agricultural and horse operations” (Elinstallationer i lantbruk och hästverksamhet 2019:1 Rev 2022)

** In corrosive environments, both luminaires and fasteners must be able to withstand corrosion. Plastic luminaires must be intended for the environment in question. The plastic may need to withstand detergents and corrosive gases such as ammonia. E.g. cattle stalls, pig stalls, poultry stalls, car washes, lubrication pits, public baths or the like.
