IP06 vs IP28
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP06 and IP28 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 2) and liquid protection (level 6 vs 8). IP06 is rated for no protection and powerful water jets (12.5 mm nozzle), while IP28 provides > 12.5 mm — finger and continuous immersion (manufacturer-specified).
With IP06, an enclosure receives no protection against solid objects 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 0 with second-digit (liquid) level 6.
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 (IP06 vs IP28)
Solid protection
IP06
Level 0 — No Protection
IP28
Level 2 — > 12.5 mm — Finger
IP06 provides "No Protection" (level 0), while IP28 provides "> 12.5 mm — Finger" (level 2). IP28 is 2 levels higher.
Liquid protection
IP06
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP28
Level 8 — Continuous Immersion (manufacturer-specified)
IP06 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP28 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP28 provides 2 levels more liquid protection.

Recommendation
IP28 offers higher overall protection than IP06. Choose IP28 for harsher environments; IP06 may suffice for milder conditions and can be more cost-effective.
