IP57 vs IP58
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP57 and IP58 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 7 vs 8). IP57 is rated for dust-protected and temporary immersion (up to 1 m), while IP58 provides dust-protected and continuous immersion (manufacturer-specified).
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.
IP58 is dust-protected and rated for continuous immersion in water under manufacturer-specified conditions. A niche rating for equipment that must operate submerged while allowing limited dust ingress.

The exact difference (IP57 vs IP58)
Solid protection
IP57
Level 5 — Dust-Protected
IP58
Level 5 — Dust-Protected
Both IP57 and IP58 share the same solid protection: Dust-Protected.
Liquid protection
IP57
Level 7 — Temporary Immersion (up to 1 m)
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP57 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP58 provides 1 level more liquid protection.

Recommendation
IP58 offers higher overall protection than IP57. Choose IP58 for harsher environments; IP57 may suffice for milder conditions and can be more cost-effective.
