IP04 vs IP36
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP04 and IP36 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 4 vs 6). IP04 is rated for no protection and splashing water (all directions), while IP36 provides > 2.5 mm — tool / wire and powerful water jets (12.5 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.
The IP36 classification guarantees protection against solid objects larger than 2.5 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 3 with second-digit (liquid) level 6.

The exact difference (IP04 vs IP36)
Solid protection
IP04
Level 0 — No Protection
IP36
Level 3 — > 2.5 mm — Tool / Wire
IP04 provides "No Protection" (level 0), while IP36 provides "> 2.5 mm — Tool / Wire" (level 3). IP36 is 3 levels higher.
Liquid protection
IP04
Level 4 — Splashing Water (all directions)
IP36
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP04 handles 50–100 kPa (Splashing Water (all directions)), while IP36 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP36 provides 2 levels more liquid protection.

Recommendation
IP36 offers higher overall protection than IP04. Choose IP36 for harsher environments; IP04 may suffice for milder conditions and can be more cost-effective.
