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 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.

IP measures how well a device is protected from both solid objects and liquids. For example, for IP57 and IP67, the first digit tells us how well the product is protected from solids. The second digit is about how resistant the product is to water.

IP Rating Chart

Dust (First Number)Moisture (Second Number)
IP 0x – No Protection
IP 1x – Objects ≥ 50mm
IP 2x – Objects ≥ 12mm
IP 3x – Objects ≥ 2.5mm
IP 4x – Objects ≥ 1mm
IP 5x – Dust Protected
IP 6x – Dust Tight
IP x0 – No Protection
IP x1 – Vertically Dripping Water
IP x2 – 15 Degrees Tilt Dripping Water
IP x3 – Sprayed Water
IP x4 – Splashed Water
IP x5 – Water Jets
IP x6 – Powerful Water Jets
IP x7 – Effects of Immersion
IP x8 – Indefinite Immersion
IP x9 – High pressure, high temperature
water jetting

IPX9K testing to ISO 20653 – Road vehicles – Degrees of protection (IP code) – Protection of electrical equipment against foreign objects, water, and access
