IP05 vs IP36
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP36 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 5 vs 6). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP36 provides > 2.5 mm — tool / wire 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.
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 (IP05 vs IP36)
Solid protection
IP05
Level 0 — No Protection
IP36
Level 3 — > 2.5 mm — Tool / Wire
IP05 provides "No Protection" (level 0), while IP36 provides "> 2.5 mm — Tool / Wire" (level 3). IP36 is 3 levels higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP36
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP36 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP36 provides 1 level more liquid protection.

Recommendation
IP36 offers higher overall protection than IP05. Choose IP36 for harsher environments; IP05 may suffice for milder conditions and can be more cost-effective.
