IP52 vs IP56
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP52 and IP56 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 2 vs 6). IP52 is rated for dust-protected and dripping water at 15° tilt, while IP56 provides dust-protected and powerful water jets (12.5 mm nozzle).
IP52 is an ingress protection code that ensures dust-protected (limited ingress, no harmful deposit) and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 5 with second-digit (liquid) level 2.
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 (IP52 vs IP56)
Solid protection
IP52
Level 5 — Dust-Protected
IP56
Level 5 — Dust-Protected
Both IP52 and IP56 share the same solid protection: Dust-Protected.
Liquid protection
IP52
Level 2 — Dripping Water at 15° Tilt
IP56
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP52 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt), while IP56 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP56 provides 4 levels more liquid protection.

No direct NEMA equivalent.
Recommendation
IP56 offers higher overall protection than IP52. Choose IP56 for harsher environments; IP52 may suffice for milder conditions and can be more cost-effective.
