IP25 vs IP35
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP25 and IP35 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 3). IP25 is rated for > 12.5 mm — finger and water jets (6.3 mm nozzle), while IP35 provides > 2.5 mm — tool / wire and water jets (6.3 mm nozzle).
IP25 is an ingress protection code that ensures protection against solid objects larger than 12.5 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.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 5.
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 (IP25 vs IP35)
Solid protection
IP25
Level 2 — > 12.5 mm — Finger
IP35
Level 3 — > 2.5 mm — Tool / Wire
IP25 provides "> 12.5 mm — Finger" (level 2), while IP35 provides "> 2.5 mm — Tool / Wire" (level 3). IP35 is 1 level higher.
Liquid protection
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP35
Level 5 — Water Jets (6.3 mm nozzle)
Both IP25 and IP35 share the same liquid protection: Water Jets (6.3 mm nozzle).

Recommendation
IP35 offers higher overall protection than IP25. Choose IP35 for harsher environments; IP25 may suffice for milder conditions and can be more cost-effective.
