IP67 vs IP03
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP67 and IP03 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 0) and liquid protection (level 7 vs 3). IP67 is rated for dust-tight and temporary immersion (up to 1 m), while IP03 provides no protection and spraying water (up to 60°).
IP67 is dust-tight and withstands temporary immersion in water up to 1 meter for 30 minutes. The go-to rating for outdoor and rugged devices that may be briefly submerged.
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.

The exact difference (IP67 vs IP03)
Solid protection
IP67
Level 6 — Dust-Tight
IP03
Level 0 — No Protection
IP67 provides "Dust-Tight" (level 6), while IP03 provides "No Protection" (level 0). IP67 is 6 levels higher.
Liquid protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP03
Level 3 — Spraying Water (up to 60°)
IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP03 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP67 provides 4 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP03. Choose IP67 for harsher environments; IP03 may suffice for milder conditions and can be more cost-effective.
