IP12 vs IP16
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP12 and IP16 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 2 vs 6). IP12 is rated for > 50 mm — back of hand and dripping water at 15° tilt, while IP16 provides > 50 mm — back of hand and powerful water jets (12.5 mm nozzle).
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.
IP16 is an ingress protection code that ensures protection against solid objects larger than 50 mm and protection against powerful water jets. Water projected in powerful jets by a 12.5 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 1 with second-digit (liquid) level 6.

The exact difference (IP12 vs IP16)
Solid protection
IP12
Level 1 — > 50 mm — Back of Hand
IP16
Level 1 — > 50 mm — Back of Hand
Both IP12 and IP16 share the same solid protection: > 50 mm — Back of Hand.
Liquid protection
IP12
Level 2 — Dripping Water at 15° Tilt
IP16
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP12 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP16 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP16 provides 4 levels more liquid protection.

Recommendation
IP16 offers higher overall protection than IP12. Choose IP16 for harsher environments; IP12 may suffice for milder conditions and can be more cost-effective.
