IP13 vs IP16
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP13 and IP16 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 3 vs 6). IP13 is rated for > 50 mm — back of hand and spraying water (up to 60°), while IP16 provides > 50 mm — back of hand and powerful water jets (12.5 mm nozzle).
The IP13 rating offers protection against solid objects larger than 50 mm and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 1 with second-digit (liquid) level 3.
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 (IP13 vs IP16)
Solid protection
IP13
Level 1 — > 50 mm — Back of Hand
IP16
Level 1 — > 50 mm — Back of Hand
Both IP13 and IP16 share the same solid protection: > 50 mm — Back of Hand.
Liquid protection
IP13
Level 3 — Spraying Water (up to 60°)
IP16
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP13 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP16 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP16 provides 3 levels more liquid protection.

Recommendation
IP16 offers higher overall protection than IP13. Choose IP16 for harsher environments; IP13 may suffice for milder conditions and can be more cost-effective.
