IP57 vs IP64
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP57 and IP64 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6) and liquid protection (level 7 vs 4). IP57 is rated for dust-protected and temporary immersion (up to 1 m), while IP64 provides dust-tight and splashing water (all directions).
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.
IP64 is dust-tight and resists splashing water from any direction. A solid outdoor-covered rating combining complete dust exclusion with splash tolerance, sitting between IP65 (jets) and IP54 (dust-protected).

The exact difference (IP57 vs IP64)
Solid protection
IP57
Level 5 — Dust-Protected
IP64
Level 6 — Dust-Tight
IP57 provides "Dust-Protected" (level 5), while IP64 provides "Dust-Tight" (level 6). IP64 is 1 level higher.
Liquid protection
IP57
Level 7 — Temporary Immersion (up to 1 m)
IP64
Level 4 — Splashing Water (all directions)
IP57 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP64 handles 50–100 kPa (Splashing Water (all directions)). IP57 provides 3 levels more liquid protection.

Recommendation
IP57 offers higher overall protection than IP64. Choose IP57 for harsher environments; IP64 may suffice for milder conditions and can be more cost-effective.
