The IP rating system is critical in a vast array of industries to ensure safety, reliability, and longevity.
This standard applies to the classification of electrical equipment with a rated voltage not exceeding 72.5 kV, and any manufacturer looking to sell electronic devices in international markets will need to comply with it. It's the definitive guide for testing and rating enclosures used in everything from consumer smartphones to industrial control panels.
