IP & IK Ratings Guide

Ingress Protection (IP) Ratings Guide

At LSI Industries, the IP Ratings Guide is central to our lighting solutions’ design and longevity.

Each fixture undergoes rigorous assessment for resistance against elements, from water ingress to dust and insect intrusion. For instance, a rating of IP65 ensures dust-tight protection and resistance against water jets, while IP68 guarantees dust protection and capability for continuous submersion in water. Use the IP Ratings Guide below and trust in LSI’s commitment to providing products that not only meet but exemplify industry standards.

NSF Certifications

NSF Certification

Description of Locations/Use and Commentary

Typical Lighting Applications

Non-Food Zone Area where direct contact with food products during normal operations would not be expected. Equipment is located outside the normal washdown area. There is a concern that the fixture will add contamination to the protected space or food product (e.g., cleanability–will the finish withstand cleaning, chipping paint, deteriorating paints or finishes, lens impact resistance, lamp breakage, etc.). Kitchens: Food Storage; Dry process area; Damp process areas–no drip possibility
Splash Zone Area where direct contact with food products during normal operations would not be expected; however, the fixture may be situated such that liquids used in the processing or cleaning procedures, may splash, spill, or otherwise soil–either intentionally or inadvertently–the surface of the fixture. There then is the potential for dripping or draining onto other surfaces or even the process. Since these fixtures are often used in washdown areas. Wet location listing is not sufficient. Fixtures must be tested to withstand high pressure hose washdown. The concerns of Non-Food Zone also apply. Wet or damp process areas; high pressure purging and/or decontamination used in the process; Areas using hose washdown
Food Zone Area where direct contact with food products is normally expected and surfaces from which the food may drip, drain, or splash back onto surfaces normally in contact with food. Equipment other than lighting fixtures typically require this certification (e.g. work tables cutting boards, others direct contact equipment). Category not typically used for lighting

 

Impact Protection (IK) Ratings Guide

Understanding the IK Rating In Our Lighting Solutions:

The IK rating represents the robustness of an enclosure against external mechanical impacts, ensuring our lighting products stand the test of time in even the most challenging environments. Defined by the international standard IEC 62262, this rating offers a clear measure of how well a product can resist potential damage from accidental knocks, bumps, or any other physical impacts.

How Do We Measure It?

Each product’s IK rating is derived from rigorous testing procedures where it’s subjected to impacts of varying energy levels, measured in joules. For instance, an IK10-rated light has demonstrated the capacity to withstand a powerful 20 joules impact, guaranteeing exceptional durability. When you choose our lighting solutions, you’re not just choosing brilliance; you’re opting for unmatched resilience.
