Protection: IP & IK Ratings

It’s important to understand IP and IK ratings, as they play a critical role in determining the suitability of luminaires for various environments. These ratings are used to assess the protection levels of luminaires against various environmental factors, such as moisture, dust, and impact. In this article, we’ll take a closer look at what IP and IK ratings are, and how they are used to evaluate the performance and durability of luminaires.

IP RATINGS

IP, which stands for “Ingress Protection,” is a rating system used to evaluate the level of protection provided by a luminaire against dust and water. The IP rating is comprised of two numbers: the first number indicates the level of protection against solid particles, such as dust, and the second number indicates the level of protection against moisture, such as water.

For example, an IP65 rating means that the luminaire is dust-tight and protected against low-pressure water jets from any direction. An IP67 rating means that the fixture is dust-tight and protected against immersion in water for up to 30 minutes. The higher the IP rating, the better the protection against dust and water.

IK RATINGS

IK, which stands for “Impact Resistance,” is a rating system used to evaluate the ability of a luminaire to resist damage from impact. The IK rating is expressed as a single digit, with a higher number indicating a higher level of impact resistance.

For example, an IK08 rating means that the luminaire can withstand a 5-joule impact, while an IK10 rating means that the fixture can withstand a 10-joule impact. The higher the IK rating, the better the protection against impact.

These ratings are determined through a controlled testing process outlined in the IEC 62262 standard. During testing, luminaires are subjected to various levels of impact force, simulating real-world conditions where they may be exposed to accidental blows, vandalism, or other mechanical stresses.

WHY ARE IP & IK RATINGS IMPORTANT?

IP and IK ratings are important because they provide a standardised method of evaluating the durability and performance of luminaires in various environments. These ratings help ensure that luminaires are suitable for their intended use and that they can withstand the environmental conditions in which they will be installed.

For example, if a luminaire is intended for use in a damp or wet location, such as a bathroom or outdoor area, it must have a high IP rating to ensure it is protected against moisture. Similarly, if a luminaire is intended for use in an area where it may be subject to impact, such as a warehouse or sports facility, it must have a high IK rating to ensure that it can withstand impacts without breaking.

IP and IK ratings are critical factors to consider when choosing luminaires for commercial or industrial environments. These ratings provide a standard method of evaluating the durability and performance of luminaires in various conditions and help ensure that they are suitable for their intended use and can withstand the environmental conditions in which they will be installed.
