IP22 vs IP05
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP22 and IP05 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 0) and liquid protection (level 2 vs 5). IP22 is rated for > 12.5 mm — finger and dripping water at 15° tilt, while IP05 provides no protection and water jets (6.3 mm nozzle).
IP22 protects against fingers and 12.5 mm objects, plus vertically dripping water when tilted up to 15°. Common for indoor equipment that may encounter occasional condensation or drips.
Under IEC 60529, IP05 specifies no protection against solid objects and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 5.

The exact difference (IP22 vs IP05)
Solid protection
IP22
Level 2 — > 12.5 mm — Finger
IP05
Level 0 — No Protection
IP22 provides "> 12.5 mm — Finger" (level 2), while IP05 provides "No Protection" (level 0). IP22 is 2 levels higher.
Liquid protection
IP22
Level 2 — Dripping Water at 15° Tilt
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP22 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP05 provides 3 levels more liquid protection.

Recommendation
IP05 offers higher overall protection than IP22. Choose IP05 for harsher environments; IP22 may suffice for milder conditions and can be more cost-effective.
