IP05 vs IP34
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP34 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 5 vs 4). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP34 provides > 2.5 mm — tool / wire and splashing water (all directions).
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.
IP34 is an ingress protection code that ensures protection against solid objects larger than 2.5 mm 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 3 with second-digit (liquid) level 4.

The exact difference (IP05 vs IP34)
Solid protection
IP05
Level 0 — No Protection
IP34
Level 3 — > 2.5 mm — Tool / Wire
IP05 provides "No Protection" (level 0), while IP34 provides "> 2.5 mm — Tool / Wire" (level 3). IP34 is 3 levels higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP34
Level 4 — Splashing Water (all directions)
IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP34 handles 50–100 kPa (Splashing Water (all directions)). IP05 provides 1 level more liquid protection.

Recommendation
IP34 offers higher overall protection than IP05. Choose IP34 for harsher environments; IP05 may suffice for milder conditions and can be more cost-effective.
