IP05 vs IP57
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP57 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 5) and liquid protection (level 5 vs 7). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP57 provides dust-protected and temporary immersion (up to 1 m).
Under IEC 60529, IP05 specifies no protection against solid objects and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 5.
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 (IP05 vs IP57)
Solid protection
IP05
Level 0 — No Protection
IP57
Level 5 — Dust-Protected
IP05 provides "No Protection" (level 0), while IP57 provides "Dust-Protected" (level 5). IP57 is 5 levels higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP57
Level 7 — Temporary Immersion (up to 1 m)
IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP57 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP57 provides 2 levels more liquid protection.

Recommendation
IP57 offers higher overall protection than IP05. Choose IP57 for harsher environments; IP05 may suffice for milder conditions and can be more cost-effective.
