Breaking Down the Ingress Protection (IP) Rating System
What is an IP Rating?
IP ratings are used to determine how effectively a fixture is sealed to prevent intrusion against foreign objects (sand, dirt, etc.) and moisture. Fixtures are measured on a two-tier scale. The first test for intrusion protection and the second test is for moisture protection; each test yields its unique rating.
What do the numbers in an IP Rating mean?
The numbers that correspond with Ingress Protection each have a specific meaning (see chart below). The first number indicates the degree of protection from moving parts (tools), as well as the protection of enclosed equipment from foreign objects (soil, pests, etc.). The second number defines the protection level from various forms of moisture (drips, sprays, submersion, etc.). The table below should help to elaborate:
Why do we test for IP Ratings?
The standards aim to provide our customers with more detailed information than vague statements such as “built for the outdoors” or “super-strong.” Through these tests, we ensure that vital parts of fixtures are protected from physical damage and the intrusion of moisture. Only after this rigorous testing is completed are we proud to claim that we offer highly durable, water-resistant, and even industry-leading IP68 rated fixtures.
