IP00 vs IP16
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP00 and IP16 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 1) and liquid protection (level 0 vs 6). IP00 is rated for no protection and no protection, while IP16 provides > 50 mm — back of hand and powerful water jets (12.5 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.
IP16 is an ingress protection code that ensures protection against solid objects larger than 50 mm and protection against powerful water jets. Water projected in powerful jets by a 12.5 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 1 with second-digit (liquid) level 6.

The exact difference (IP00 vs IP16)
Solid protection
IP00
Level 0 — No Protection
IP16
Level 1 — > 50 mm — Back of Hand
IP00 provides "No Protection" (level 0), while IP16 provides "> 50 mm — Back of Hand" (level 1). IP16 is 1 level higher.
Liquid protection
IP00
Level 0 — No Protection
IP16
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP00 provides "No Protection" (level 0), while IP16 provides "Powerful Water Jets (12.5 mm nozzle)" (level 6). IP16 is 6 levels higher.

Recommendation
IP16 offers higher overall protection than IP00. Choose IP16 for harsher environments; IP00 may suffice for milder conditions and can be more cost-effective.
