IP05 vs IP43
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP43 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 4) and liquid protection (level 5 vs 3). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP43 provides > 1 mm — small wires and spraying water (up to 60°).
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.
IP43 protects against 1 mm solid objects and spraying water up to 60° from vertical. A practical rating for sheltered equipment subject to light angled spray, such as covered outdoor fixtures.

The exact difference (IP05 vs IP43)
Solid protection
IP05
Level 0 — No Protection
IP43
Level 4 — > 1 mm — Small Wires
IP05 provides "No Protection" (level 0), while IP43 provides "> 1 mm — Small Wires" (level 4). IP43 is 4 levels higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP43
Level 3 — Spraying Water (up to 60°)
IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP43 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)). IP05 provides 2 levels more liquid protection.

Recommendation
IP43 offers higher overall protection than IP05. Choose IP43 for harsher environments; IP05 may suffice for milder conditions and can be more cost-effective.
