IP58 vs IP64
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP64 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6) and liquid protection (level 8 vs 4). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP64 provides dust-tight and splashing water (all directions).
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.
IP64 is dust-tight and resists splashing water from any direction. A solid outdoor-covered rating combining complete dust exclusion with splash tolerance, sitting between IP65 (jets) and IP54 (dust-protected).

The exact difference (IP58 vs IP64)
Solid protection
IP58
Level 5 — Dust-Protected
IP64
Level 6 — Dust-Tight
IP58 provides "Dust-Protected" (level 5), while IP64 provides "Dust-Tight" (level 6). IP64 is 1 level higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP64
Level 4 — Splashing Water (all directions)
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP64 handles 50–100 kPa (Splashing Water (all directions)). IP58 provides 4 levels more liquid protection.

Recommendation
IP58 offers higher overall protection than IP64. Choose IP58 for harsher environments; IP64 may suffice for milder conditions and can be more cost-effective.
