IP65
Last updated: Aug 9, 2026IP65 is dust-tight and resists low-pressure water jets (6.3 mm nozzle, 30 kPa). It is the most common standard for fully exposed outdoor electronics such as lighting, cameras, and EV chargers.

What IP65 means
The IP code IP65 is part of the IEC 60529 standard for ingress protection. The first characteristic numeral, 6, indicates the level of protection against solid objects and access to hazardous parts. The second numeral, 5, indicates the level of protection against the ingress of water. Together, these digits describe exactly what an enclosure rated IP65 can withstand.
For solid protection, the digit 6 means the enclosure is dust-tight. Protected against access to hazardous parts with a wire. No ingress of dust whatsoever. The test method is dust chamber (talcum powder) for 8 hours (2 hours if equipment is in operation) with enclosure under reduced internal pressure; no dust ingress permitted.
For liquid protection, the digit 5 means the enclosure resists water jets (6.3 mm nozzle). Protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects. The test procedure is standard nozzle (6.3 mm diameter) at 30 kpa, 12.5 l/min; water aimed at enclosure from all practicable directions.
IP65 vs IP66: IP66 handles stronger water jets (12.5 mm nozzle, 100 kPa). IP65 vs IP67: IP67 adds temporary immersion. When specifying IP65 for a project, confirm the rating certificate from the manufacturer and consider that seals degrade over time with temperature cycling, UV exposure, and chemical contact.
