IP52 vs IP57
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP52 and IP57 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 2 vs 7). IP52 is rated for dust-protected and dripping water at 15° tilt, while IP57 provides dust-protected and temporary immersion (up to 1 m).
IP52 is an ingress protection code that ensures dust-protected (limited ingress, no harmful deposit) and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 5 with second-digit (liquid) level 2.
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.

The exact difference (IP52 vs IP57)
Solid protection
IP52
Level 5 — Dust-Protected
IP57
Level 5 — Dust-Protected
Both IP52 and IP57 share the same solid protection: Dust-Protected.
Liquid protection
IP52
Level 2 — Dripping Water at 15° Tilt
IP57
Level 7 — Temporary Immersion (up to 1 m)
IP52 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP57 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP57 provides 5 levels more liquid protection.

Recommendation
IP57 offers higher overall protection than IP52. Choose IP57 for harsher environments; IP52 may suffice for milder conditions and can be more cost-effective.
