IP54 vs IP65
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP54 and IP65 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 6) and liquid protection (level 4 vs 5). IP54 is rated for dust-protected and splashing water (all directions), while IP65 provides dust-tight and water jets (6.3 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.
IP65 is dust-tight and resists low-pressure water jets (6.3 mm nozzle, 30 kPa). It is the most common standard for fully exposed outdoor electronics such as lighting, cameras, and EV chargers.

The exact difference (IP54 vs IP65)
Solid protection
IP54
Level 5 — Dust-Protected
IP65
Level 6 — Dust-Tight
IP54 provides "Dust-Protected" (level 5), while IP65 provides "Dust-Tight" (level 6). IP65 is 1 level higher.
Liquid protection
IP54
Level 4 — Splashing Water (all directions)
IP65
Level 5 — Water Jets (6.3 mm nozzle)
IP54 handles 50–100 kPa (Splashing Water (all directions)), while IP65 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP65 provides 1 level more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP65 offers higher overall protection than IP54. Choose IP65 for harsher environments; IP54 may suffice for milder conditions and can be more cost-effective.
