IP05 vs IP06
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP06 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 5 vs 6). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP06 provides no protection and powerful water jets (12.5 mm nozzle).
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.
With IP06, an enclosure receives no protection against solid objects 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 0 with second-digit (liquid) level 6.

The exact difference (IP05 vs IP06)
Solid protection
IP05
Level 0 — No Protection
IP06
Level 0 — No Protection
Both IP05 and IP06 share the same solid protection: No Protection.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP06
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP06 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP06 provides 1 level more liquid protection.

Recommendation
IP06 offers higher overall protection than IP05. Choose IP06 for harsher environments; IP05 may suffice for milder conditions and can be more cost-effective.
