IP58 vs IPX5
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IPX5 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 IPX5 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.
IPX5 resists low-pressure water jets (6.3 mm nozzle, 30 kPa) with solid protection not specified. Used where water-jet resistance matters more than dust sealing.

The exact difference (IP58 vs IPX5)
Solid protection
IP58
Level 5 — Dust-Protected
IPX5
Level 0 — No Protection
IP58 provides "Dust-Protected" (level 5), while IPX5 provides "No Protection" (level 0). IP58 is 5 levels higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IPX5
Level 5 — Water Jets (6.3 mm nozzle)
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IPX5 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP58 provides 3 levels more liquid protection.

Recommendation
IP58 offers higher overall protection than IPX5. Choose IP58 for harsher environments; IPX5 may suffice for milder conditions and can be more cost-effective.
