IP08 vs IP25
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP08 and IP25 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2) and liquid protection (level 8 vs 5). IP08 is rated for no protection and continuous immersion (manufacturer-specified), while IP25 provides > 12.5 mm — finger and water jets (6.3 mm nozzle).
Built to withstand no protection against solid objects and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. Classified as IEC 60529 ingress protection code IP08, it pairs solid level 0 with liquid level 8.
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 (IP08 vs IP25)
Solid protection
IP08
Level 0 — No Protection
IP25
Level 2 — > 12.5 mm — Finger
IP08 provides "No Protection" (level 0), while IP25 provides "> 12.5 mm — Finger" (level 2). IP25 is 2 levels higher.
Liquid protection
IP08
Level 8 — Continuous Immersion (manufacturer-specified)
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP08 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP25 handles 30 kPa (Water Jets (6.3 mm nozzle)). IP08 provides 3 levels more liquid protection.

Recommendation
IP08 offers higher overall protection than IP25. Choose IP08 for harsher environments; IP25 may suffice for milder conditions and can be more cost-effective.
