IP00 vs IP25
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP00 and IP25 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2) and liquid protection (level 0 vs 5). IP00 is rated for no protection and no protection, while IP25 provides > 12.5 mm — finger and water jets (6.3 mm nozzle).
IP00 offers no protection against solid objects or moisture. It is suitable only for indoor, climate-controlled environments where the equipment is fully enclosed within another protective housing.
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 (IP00 vs IP25)
Solid protection
IP00
Level 0 — No Protection
IP25
Level 2 — > 12.5 mm — Finger
IP00 provides "No Protection" (level 0), while IP25 provides "> 12.5 mm — Finger" (level 2). IP25 is 2 levels higher.
Liquid protection
IP00
Level 0 — No Protection
IP25
Level 5 — Water Jets (6.3 mm nozzle)
IP00 provides "No Protection" (level 0), while IP25 provides "Water Jets (6.3 mm nozzle)" (level 5). IP25 is 5 levels higher.

Recommendation
IP25 offers higher overall protection than IP00. Choose IP25 for harsher environments; IP00 may suffice for milder conditions and can be more cost-effective.
