IP57 vs IP01
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP57 and IP01 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 0) and liquid protection (level 7 vs 1). IP57 is rated for dust-protected and temporary immersion (up to 1 m), while IP01 provides no protection and vertically dripping water.
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.
IP01 provides no protection against solid objects and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 1.

The exact difference (IP57 vs IP01)
Solid protection
IP57
Level 5 — Dust-Protected
IP01
Level 0 — No Protection
IP57 provides "Dust-Protected" (level 5), while IP01 provides "No Protection" (level 0). IP57 is 5 levels higher.
Liquid protection
IP57
Level 7 — Temporary Immersion (up to 1 m)
IP01
Level 1 — Vertically Dripping Water
IP57 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP01 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP57 provides 6 levels more liquid protection.

Recommendation
IP57 offers higher overall protection than IP01. Choose IP57 for harsher environments; IP01 may suffice for milder conditions and can be more cost-effective.
