IP58 vs IP47
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP58 and IP47 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 4) and liquid protection (level 8 vs 7). IP58 is rated for dust-protected and continuous immersion (manufacturer-specified), while IP47 provides > 1 mm — small wires and temporary immersion (up to 1 m).
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.
IP47 provides protection against solid objects larger than 1.0 mm and protection against the effects of temporary immersion in water. Ingress of water in quantities causing harmful effects shall not be possible.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 4 with second-digit (liquid) level 7.

The exact difference (IP58 vs IP47)
Solid protection
IP58
Level 5 — Dust-Protected
IP47
Level 4 — > 1 mm — Small Wires
IP58 provides "Dust-Protected" (level 5), while IP47 provides "> 1 mm — Small Wires" (level 4). IP58 is 1 level higher.
Liquid protection
IP58
Level 8 — Continuous Immersion (manufacturer-specified)
IP47
Level 7 — Temporary Immersion (up to 1 m)
IP58 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP47 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP58 provides 1 level more liquid protection.

Recommendation
IP58 offers higher overall protection than IP47. Choose IP58 for harsher environments; IP47 may suffice for milder conditions and can be more cost-effective.
