IP58 vs IP05
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP05 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 0) and liquid protection (level 8 vs 5). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP05 provides no protection and water jets (6.3 mm nozzle).
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.
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.

The exact difference (IP58 vs IP05)
Solid protection
IP58
Level 5 — Dust-Protected
IP05
Level 0 — No Protection
IP58 provides "Dust-Protected" (level 5), while IP05 provides "No Protection" (level 0). IP58 is 5 levels higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)). 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.
