IP60 vs IP66
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP60 and IP66 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 0 vs 6). IP60 is rated for dust-tight and no protection, while IP66 provides dust-tight and powerful water jets (12.5 mm nozzle).
IP60 is dust-tight with no water protection. Used for indoor equipment in very dusty environments that stays completely dry — dust exclusion without any moisture tolerance.
IP66 is dust-tight and resists powerful water jets (12.5 mm nozzle, 100 kPa). A robust outdoor rating for equipment exposed to heavy rain, storms, or directed high-pressure hosing (but not high-pressure washdown).

Level 6 — Dust-Tight
IP66
Level 6 — Dust-Tight
Both IP60 and IP66 share the same solid protection: Dust-Tight.
Liquid protection
IP60
Level 0 — No Protection
IP66
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP60 provides "No Protection" (level 0), while IP66 provides "Powerful Water Jets (12.5 mm nozzle)" (level 6). IP66 is 6 levels higher.

Recommendation
IP66 offers higher overall protection than IP60. Choose IP66 for harsher environments; IP60 may suffice for milder conditions and can be more cost-effective.
