IP04 vs IP35
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP04 and IP35 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 4 vs 5). IP04 is rated for no protection and splashing water (all directions), while IP35 provides > 2.5 mm — tool / wire and water jets (6.3 mm nozzle).
The IP04 rating offers no protection against solid objects and protection against splashing water. Water splashed 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 4.
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 (IP04 vs IP35)
Solid protection
IP04
Level 0 — No Protection
IP35
Level 3 — > 2.5 mm — Tool / Wire
IP04 provides "No Protection" (level 0), while IP35 provides "> 2.5 mm — Tool / Wire" (level 3). IP35 is 3 levels higher.
Liquid protection
IP04
Level 4 — Splashing Water (all directions)
IP35
Level 5 — Water Jets (6.3 mm nozzle)
IP04 handles 50–100 kPa (Splashing Water (all directions)), while IP35 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP35 provides 1 level more liquid protection.

Recommendation
IP35 offers higher overall protection than IP04. Choose IP35 for harsher environments; IP04 may suffice for milder conditions and can be more cost-effective.
