IP58 vs IP04
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP04 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 0) and liquid protection (level 8 vs 4). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP04 provides no protection 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.
The IP04 rating offers no protection against solid objects and protection against splashing water. Water splashed against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 4.

The exact difference (IP58 vs IP04)
Solid protection
IP58
Level 5 — Dust-Protected
IP04
Level 0 — No Protection
IP58 provides "Dust-Protected" (level 5), while IP04 provides "No Protection" (level 0). IP58 is 5 levels higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP04
Level 4 — Splashing Water (all directions)
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP04 handles 50–100 kPa (Splashing Water (all directions)). IP58 provides 4 levels more liquid protection.

Recommendation
IP58 offers higher overall protection than IP04. Choose IP58 for harsher environments; IP04 may suffice for milder conditions and can be more cost-effective.
