IP13 vs IP56
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP13 and IP56 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 5) and liquid protection (level 3 vs 6). IP13 is rated for > 50 mm — back of hand and spraying water (up to 60°), while IP56 provides dust-protected and powerful water jets (12.5 mm nozzle).
The IP13 rating offers protection against solid objects larger than 50 mm and protection against spraying water. Water sprayed at an angle up to 60° on either side of the vertical shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 1 with second-digit (liquid) level 3.
IP56 is dust-protected and resists powerful water jets (12.5 mm nozzle, 100 kPa). Suited to outdoor equipment subjected to heavy rain or hose-directed water.

The exact difference (IP13 vs IP56)
Solid protection
IP13
Level 1 — > 50 mm — Back of Hand
IP56
Level 5 — Dust-Protected
IP13 provides "> 50 mm — Back of Hand" (level 1), while IP56 provides "Dust-Protected" (level 5). IP56 is 4 levels higher.
Liquid protection
IP13
Level 3 — Spraying Water (up to 60°)
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP13 handles 80 kPa (tube) / 50 kPa (nozzle) (Spraying Water (up to 60°)), while IP56 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP56 provides 3 levels more liquid protection.

No direct NEMA equivalent.
Recommendation
IP56 offers higher overall protection than IP13. Choose IP56 for harsher environments; IP13 may suffice for milder conditions and can be more cost-effective.
