The Difference in Waterproof Levels between IP64, IP65, IP66, IP67, IP68, and IP69

The Difference in Waterproof Levels between IP64, IP65, IP66, IP67, IP68, and IP69

The IP (Ingress Protection) rating system, established by the International Electrotechnical Commission (IEC), evaluates a device's resistance to solid particles and liquid ingress. An IP rating consists of "IP" followed by two digits: the first denotes dust protection, and the second indicates water resistance. Below is a comparison of the waterproof capabilities among IP64, IP65, IP66, IP67, IP68, and IP69 ratings:

• IP64: Offers dust protection level 6 (complete dustproofing) and water protection level 4 (protection against splashing water from any direction).
• IP65: Features dust protection level 6 and water protection level 5 (protection against water jets projected from a nozzle in any direction without harmful effects).
• IP66: Includes dust protection level 6 and water protection level 6 (protection against powerful water jets from any direction without harmful effects).
• IP67: Provides dust protection level 6 and water protection level 7 (protection against immersion in water up to 1 meter deep for a specified duration without damage).
• IP68: Ensures dust protection level 6 and water protection level 8 (protection against prolonged immersion under high pressure at depths exceeding 2 meters without damage).
• IP69: Combines dust protection level 6 with water protection level 9 (protection against high-pressure, high-temperature water jets from any direction without harmful effects).

Higher numbers in the IP rating indicate greater protection. For instance, an IP68-rated device offers complete dustproofing and can withstand extended submersion under pressure without damage.
