IP05 vs IP58
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP58 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 5) and liquid protection (level 5 vs 8). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP58 provides dust-protected and continuous immersion (manufacturer-specified).
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.
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 (IP05 vs IP58)
Solid protection
IP05
Level 0 — No Protection
IP58
Level 5 — Dust-Protected
IP05 provides "No Protection" (level 0), while IP58 provides "Dust-Protected" (level 5). IP58 is 5 levels higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP58 provides 3 levels more liquid protection.

Recommendation
IP58 offers higher overall protection than IP05. Choose IP58 for harsher environments; IP05 may suffice for milder conditions and can be more cost-effective.
