IP25 vs IP52
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP25 and IP52 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 5) and liquid protection (level 5 vs 2). IP25 is rated for > 12.5 mm — finger and water jets (6.3 mm nozzle), while IP52 provides dust-protected and dripping water at 15° tilt.
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.
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.

The exact difference (IP25 vs IP52)
Solid protection
IP25
Level 2 — > 12.5 mm — Finger
IP52
Level 5 — Dust-Protected
IP25 provides "> 12.5 mm — Finger" (level 2), while IP52 provides "Dust-Protected" (level 5). IP52 is 3 levels higher.
Liquid protection
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP52
Level 2 — Dripping Water at 15° Tilt
IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP52 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP25 provides 3 levels more liquid protection.

Recommendation
IP25 and IP52 offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
