IP36 vs IP47
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP36 and IP47 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 3 vs 4) and liquid protection (level 6 vs 7). IP36 is rated for > 2.5 mm — tool / wire and powerful water jets (12.5 mm nozzle), while IP47 provides > 1 mm — small wires and temporary immersion (up to 1 m).
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.
IP47 provides protection against solid objects larger than 1.0 mm and protection against the effects of temporary immersion in water. Ingress of water in quantities causing harmful effects shall not be possible.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 4 with second-digit (liquid) level 7.

The exact difference (IP36 vs IP47)
Solid protection
IP36
Level 3 — > 2.5 mm — Tool / Wire
IP47
Level 4 — > 1 mm — Small Wires
IP36 provides "> 2.5 mm — Tool / Wire" (level 3), while IP47 provides "> 1 mm — Small Wires" (level 4). IP47 is 1 level higher.
Liquid protection
IP36
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP47
Level 7 — Temporary Immersion (up to 1 m)
IP36 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP47 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)). IP47 provides 1 level more liquid protection.

Recommendation
IP47 offers higher overall protection than IP36. Choose IP47 for harsher environments; IP36 may suffice for milder conditions and can be more cost-effective.
