IP56 vs IP01
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP56 and IP01 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 0) and liquid protection (level 6 vs 1). IP56 is rated for dust-protected and powerful water jets (12.5 mm nozzle), while IP01 provides no protection and vertically dripping water.
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.
IP01 provides no protection against solid objects and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 1.

The exact difference (IP56 vs IP01)
Solid protection
IP56
Level 5 — Dust-Protected
IP01
Level 0 — No Protection
IP56 provides "Dust-Protected" (level 5), while IP01 provides "No Protection" (level 0). IP56 is 5 levels higher.
Liquid protection
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP01
Level 1 — Vertically Dripping Water
IP56 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP01 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP56 provides 5 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP56 offers higher overall protection than IP01. Choose IP56 for harsher environments; IP01 may suffice for milder conditions and can be more cost-effective.
