IP03 vs IP65
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP03 and IP65 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 6) and liquid protection (level 3 vs 5). IP03 is rated for no protection and spraying water (up to 60°), while IP65 provides dust-tight and water jets (6.3 mm nozzle).
Designed for environments requiring no protection against solid objects and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects., IP03 is an IEC 60529 code combining solid level 0 with liquid level 3.
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 (IP03 vs IP65)
Solid protection
IP03
Level 0 — No Protection
IP65
Level 6 — Dust-Tight
IP03 provides "No Protection" (level 0), while IP65 provides "Dust-Tight" (level 6). IP65 is 6 levels higher.
Liquid protection
IP03
Level 3 — Spraying Water (up to 60°)
IP65
Level 5 — Water Jets (6.3 mm nozzle)
IP03 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP65 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP65 provides 2 levels more liquid protection.

Recommendation
IP65 offers higher overall protection than IP03. Choose IP65 for harsher environments; IP03 may suffice for milder conditions and can be more cost-effective.
