IP05 vs IP12
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP12 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 1) and liquid protection (level 5 vs 2). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP12 provides > 50 mm — back of hand and dripping water at 15° tilt.
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.
Designed for environments requiring protection against solid objects larger than 50 mm and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position., IP12 is an IEC 60529 code combining solid level 1 with liquid level 2.

The exact difference (IP05 vs IP12)
Solid protection
IP05
Level 0 — No Protection
IP12
Level 1 — > 50 mm — Back of Hand
IP05 provides "No Protection" (level 0), while IP12 provides "> 50 mm — Back of Hand" (level 1). IP12 is 1 level higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP12
Level 2 — Dripping Water at 15° Tilt
IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP12 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP05 provides 3 levels more liquid protection.

Recommendation
IP05 offers higher overall protection than IP12. Choose IP05 for harsher environments; IP12 may suffice for milder conditions and can be more cost-effective.
