IP25 vs IPX8
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP25 and IPX8 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 0) and liquid protection (level 5 vs 8). IP25 is rated for > 12.5 mm — finger and water jets (6.3 mm nozzle), while IPX8 provides no protection and continuous immersion (manufacturer-specified).
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.
IPX8 protects against continuous immersion under manufacturer-specified conditions (depth and duration), with solid protection not specified. The standard for submersible consumer electronics.

The exact difference (IP25 vs IPX8)
Solid protection
IP25
Level 2 — > 12.5 mm — Finger
IPX8
Level 0 — No Protection
IP25 provides "> 12.5 mm — Finger" (level 2), while IPX8 provides "No Protection" (level 0). IP25 is 2 levels higher.
Liquid protection
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IPX8
Level 8 — Continuous Immersion (manufacturer-specified)
IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IPX8 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IPX8 provides 3 levels more liquid protection.

Recommendation
IPX8 offers higher overall protection than IP25. Choose IPX8 for harsher environments; IP25 may suffice for milder conditions and can be more cost-effective.
