IP65 vs IP64
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP65 and IP64 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 5 vs 4). IP65 is rated for dust-tight and water jets (6.3 mm nozzle), while IP64 provides dust-tight and splashing water (all directions).
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.
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 (IP65 vs IP64)
Solid protection
IP65
Level 6 — Dust-Tight
IP64
Level 6 — Dust-Tight
Both IP65 and IP64 share the same solid protection: Dust-Tight.
Liquid protection
IP65
Level 5 — Water Jets (6.3 mm nozzle)
IP64
Level 4 — Splashing Water (all directions)
IP65 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP64 handles 50–100 kPa (Splashing Water (all directions)). IP65 provides 1 level more liquid protection.

Recommendation
IP65 offers higher overall protection than IP64. Choose IP65 for harsher environments; IP64 may suffice for milder conditions and can be more cost-effective.
