IP00 vs IP28
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP00 and IP28 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2) and liquid protection (level 0 vs 8). IP00 is rated for no protection and no protection, while IP28 provides > 12.5 mm — finger and continuous immersion (manufacturer-specified).
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.
Specified under IEC 60529, IP28 denotes protection against solid objects larger than 12.5 mm and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 2 with second-digit (liquid) level 8.

The exact difference (IP00 vs IP28)
Solid protection
IP00
Level 0 — No Protection
IP28
Level 2 — > 12.5 mm — Finger
IP00 provides "No Protection" (level 0), while IP28 provides "> 12.5 mm — Finger" (level 2). IP28 is 2 levels higher.
Liquid protection
IP00
Level 0 — No Protection
IP28
Level 8 — Continuous Immersion (manufacturer-specified)
IP00 provides "No Protection" (level 0), while IP28 provides "Continuous Immersion (manufacturer-specified)" (level 8). IP28 is 8 levels higher.

Recommendation
IP28 offers higher overall protection than IP00. Choose IP28 for harsher environments; IP00 may suffice for milder conditions and can be more cost-effective.
