IP00 vs IP35
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP00 and IP35 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 0 vs 5). IP00 is rated for no protection and no protection, while IP35 provides > 2.5 mm — tool / wire 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.
Built to withstand protection against solid objects larger than 2.5 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.. Classified as IEC 60529 ingress protection code IP35, it pairs solid level 3 with liquid level 5.

The exact difference (IP00 vs IP35)
Solid protection
IP00
Level 0 — No Protection
IP35
Level 3 — > 2.5 mm — Tool / Wire
IP00 provides "No Protection" (level 0), while IP35 provides "> 2.5 mm — Tool / Wire" (level 3). IP35 is 3 levels higher.
Liquid protection
IP00
Level 0 — No Protection
IP35
Level 5 — Water Jets (6.3 mm nozzle)
IP00 provides "No Protection" (level 0), while IP35 provides "Water Jets (6.3 mm nozzle)" (level 5). IP35 is 5 levels higher.

Recommendation
IP35 offers higher overall protection than IP00. Choose IP35 for harsher environments; IP00 may suffice for milder conditions and can be more cost-effective.
