IP00 vs IP05
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP00 and IP05 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 0 vs 5). IP00 is rated for no protection and no protection, while IP05 provides no protection 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.
Under IEC 60529, IP05 specifies no protection against solid objects 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 0 with second-digit (liquid) level 5.

Level 0 — No Protection
Both IP00 and IP05 share the same solid protection: No Protection.
Liquid protection
IP00
Level 0 — No Protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP00 provides "No Protection" (level 0), while IP05 provides "Water Jets (6.3 mm nozzle)" (level 5). IP05 is 5 levels higher.

Recommendation
IP05 offers higher overall protection than IP00. Choose IP05 for harsher environments; IP00 may suffice for milder conditions and can be more cost-effective.
