IP13 vs IP35
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP13 and IP35 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 3) and liquid protection (level 3 vs 5). IP13 is rated for > 50 mm — back of hand and spraying water (up to 60°), while IP35 provides > 2.5 mm — tool / wire and water jets (6.3 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.
Built to withstand protection against solid objects larger than 2.5 mm and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP35, it pairs solid level 3 with liquid level 5.

The exact difference (IP13 vs IP35)
Solid protection
IP13
Level 1 — > 50 mm — Back of Hand
IP35
Level 3 — > 2.5 mm — Tool / Wire
IP13 provides "> 50 mm — Back of Hand" (level 1), while IP35 provides "> 2.5 mm — Tool / Wire" (level 3). IP35 is 2 levels higher.
Liquid protection
IP13
Level 3 — Spraying Water (up to 60°)
IP35
Level 5 — Water Jets (6.3 mm nozzle)
IP13 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP35 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP35 provides 2 levels more liquid protection.

Recommendation
IP35 offers higher overall protection than IP13. Choose IP35 for harsher environments; IP13 may suffice for milder conditions and can be more cost-effective.
