IP58 vs IP01
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP01 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 0) and liquid protection (level 8 vs 1). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP01 provides no protection and vertically dripping water.
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.
IP01 provides no protection against solid objects and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 1.

The exact difference (IP58 vs IP01)
Solid protection
IP58
Level 5 — Dust-Protected
IP01
Level 0 — No Protection
IP58 provides "Dust-Protected" (level 5), while IP01 provides "No Protection" (level 0). IP58 is 5 levels higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP01
Level 1 — Vertically Dripping Water
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP01 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP58 provides 7 levels more liquid protection.

Recommendation
IP58 offers higher overall protection than IP01. Choose IP58 for harsher environments; IP01 may suffice for milder conditions and can be more cost-effective.
