IP57 vs IP65
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP57 and IP65 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6) and liquid protection (level 7 vs 5). IP57 is rated for dust-protected and temporary immersion (up to 1 m), while IP65 provides dust-tight and water jets (6.3 mm nozzle).
IP57 is dust-protected and tolerates temporary immersion up to 1 m for 30 minutes. Useful for portable devices that may be dropped in shallow water.
IP65 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.

The exact difference (IP57 vs IP65)
Solid protection
IP57
Level 5 — Dust-Protected
IP65
Level 6 — Dust-Tight
IP57 provides "Dust-Protected" (level 5), while IP65 provides "Dust-Tight" (level 6). IP65 is 1 level higher.
Liquid protection
IP57
Level 7 — Temporary Immersion (up to 1 m)
IP65
Level 5 — Water Jets (6.3 mm nozzle)
IP57 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP65 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP57 provides 2 levels more liquid protection.

Recommendation
IP57 offers higher overall protection than IP65. Choose IP57 for harsher environments; IP65 may suffice for milder conditions and can be more cost-effective.
