Ingress Protection (IP) Testing

Performance Testing against Water and Dust Ingress

F2 Labs is accredited to perform Ingress Protection (IP) testing to IEC standard 60529, NEMA 250 testing, and UL 50E testing. Both UL testing and IP testing are typically performed on enclosures to determine the level of protection they provide against water, dust, ice, etc.

Ingress Protection (IP) Testing

IP testing rates and classifies the degree of protection the product provides against the intrusion of solid objects (i.e., body parts like hands and fingers), dust, accidental contact, and water in in the electrical enclosure or casing. The numbers (characteristic numerals) indicate conformity with the conditions outlined in the tables below. If there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X.
