IP58 vs IP65
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP65 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6) and liquid protection (level 8 vs 5). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP65 provides dust-tight 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.
IP65 is dust-tight and resists low-pressure water jets (6.3 mm nozzle, 30 kPa). It is the most common standard for fully exposed outdoor electronics such as lighting, cameras, and EV chargers.

The exact difference (IP58 vs IP65)
Solid protection
IP58
Level 5 — Dust-Protected
IP65
Level 6 — Dust-Tight
IP58 provides "Dust-Protected" (level 5), while IP65 provides "Dust-Tight" (level 6). IP65 is 1 level higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP65
Level 5 — Water Jets (6.3 mm nozzle)
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP65 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP58 provides 3 levels more liquid protection.

Recommendation
IP58 offers higher overall protection than IP65. Choose IP58 for harsher environments; IP65 may suffice for milder conditions and can be more cost-effective.
