IP56 vs IP25
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP56 and IP25 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 5 vs 2) and liquid protection (level 6 vs 5). IP56 is rated for dust-protected and powerful water jets (12.5 mm nozzle), while IP25 provides > 12.5 mm — finger and water jets (6.3 mm nozzle).
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.
IP25 is an ingress protection code that ensures protection against solid objects larger than 12.5 mm 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 2 with second-digit (liquid) level 5.

The exact difference (IP56 vs IP25)
Solid protection
IP56
Level 5 — Dust-Protected
IP25
Level 2 — > 12.5 mm — Finger
IP56 provides "Dust-Protected" (level 5), while IP25 provides "> 12.5 mm — Finger" (level 2). IP56 is 3 levels higher.
Liquid protection
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP56 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP56 provides 1 level more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP56 offers higher overall protection than IP25. Choose IP56 for harsher environments; IP25 may suffice for milder conditions and can be more cost-effective.
