IP04 vs IP05
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP04 and IP05 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 4 vs 5). IP04 is rated for no protection and splashing water (all directions), while IP05 provides no protection 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.
Under IEC 60529, IP05 specifies no protection against solid objects 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 0 with second-digit (liquid) level 5.

The exact difference (IP04 vs IP05)
Solid protection
IP04
Level 0 — No Protection
IP05
Level 0 — No Protection
Both IP04 and IP05 share the same solid protection: No Protection.
Liquid protection
IP04
Level 4 — Splashing Water (all directions)
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP04 handles 50–100 kPa (Splashing Water (all directions)), while IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP05 provides 1 level more liquid protection.

Recommendation
IP05 offers higher overall protection than IP04. Choose IP05 for harsher environments; IP04 may suffice for milder conditions and can be more cost-effective.
