IP58 vs IP35
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP35 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 3) and liquid protection (level 8 vs 5). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP35 provides > 2.5 mm — tool / wire 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.
Built to withstand protection against solid objects larger than 2.5 mm and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP35, it pairs solid level 3 with liquid level 5.

The exact difference (IP58 vs IP35)
Solid protection
IP58
Level 5 — Dust-Protected
IP35
Level 3 — > 2.5 mm — Tool / Wire
IP58 provides "Dust-Protected" (level 5), while IP35 provides "> 2.5 mm — Tool / Wire" (level 3). IP58 is 2 levels higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP35
Level 5 — Water Jets (6.3 mm nozzle)
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP35 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP58 provides 3 levels more liquid protection.

Recommendation
IP58 offers higher overall protection than IP35. Choose IP58 for harsher environments; IP35 may suffice for milder conditions and can be more cost-effective.
