Cracking the IK code on luminaire protection

Written by admin_stanpro | Jul 7, 2016 4:00:00 AM

The international “IK Code” measures the degree of protection against mechanical wear and tear. It is also a means to characterise the amount of impact a specific product can take.

Before the advent of the IK code, we sometimes indicated the level of impact protection with a third numeral, like IP66(9). It was closely related to the IP Code on ingress protection, but not standardized. This is one of the factors that led to the development of the IK Standard, which uses a two-numeral code to distinguish it from the old systems.

How do Scientists Measure Impact Energy?

Named for English physicist James Prescott Joule, the joule (J) is a unit of energy. It is used as a unit of work, energy and heat, and is widely used in scientific applications. 1 joule = 1 watt-second = the impact of a small apple dropped from a height of three feet

How Do we Rate Lighting Products with the IK Code?

The enclosure must withstand five hits at specified impact energies (joules) and from specified attack angles. These standard tests are conducted in a controlled environment such as a laboratory. If you wish to know if the lighting product you are looking to buy is IK-rated, refer to the product packaging, or consult the luminaire catalogue. Here is an infographic that allows you to easily visualize IK code ratings:

What IK Rating do I Need to Look for in my Lighting Application?

You don’t need a lighting product that’s highly resistant if there’s a low risk of impact to your application. First, analyze the risks of impact, and then look for the option that best fits your needs. In the case of an application for which the risk of vandalism is high, look for products that can handle it, such as IK10-rated products.

IK Rating	Description of Conditions	Recommended for
IK 07	No major risk of impact	Ideal for technical rooms
IK 08	Significant risk of impact that could damage lighting equipment	Ideal for hallways
IK10	Maximum risk of impact that might damage lighting equipment	Ideal for workshops, parks, schools, prisons…
