IP54 vs IP56
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP54 and IP56 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 4 vs 6). IP54 is rated for dust-protected and splashing water (all directions), while IP56 provides dust-protected and powerful water jets (12.5 mm nozzle).
IP54 is dust-protected (limited ingress, no harmful deposit) and resists splashing water from any direction. A versatile rating for industrial and outdoor-covered equipment in dusty, damp environments.
IP56 is dust-protected and resists powerful water jets (12.5 mm nozzle, 100 kPa). Suited to outdoor equipment subjected to heavy rain or hose-directed water.

The exact difference (IP54 vs IP56)
Solid protection
IP54
Level 5 — Dust-Protected
IP56
Level 5 — Dust-Protected
Both IP54 and IP56 share the same solid protection: Dust-Protected.
Liquid protection
IP54
Level 4 — Splashing Water (all directions)
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP54 handles 50–100 kPa (Splashing Water (all directions)), while IP56 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP56 provides 2 levels more liquid protection.

Recommendation
IP56 offers higher overall protection than IP54. Choose IP56 for harsher environments; IP54 may suffice for milder conditions and can be more cost-effective.
