IP Rating

Ingress Protection

A two-digit rating (e.g. IP65) measuring an appliance's resistance to dust and water — common on outdoor and bathroom fittings.

Ingress Protection is the IEC 60529 international standard rating for how well an enclosure resists solid objects and water. The first digit (0–6) rates dust protection; the second digit (0–9) rates water protection. IP44 is splash-proof; IP65 is dust-tight and water-jet resistant; IP67 can be submerged in water briefly. Common on outdoor lighting, bathroom appliances, solar panels and smart-home sensors.
