IP67 vs IP16
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP67 and IP16 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 1) and liquid protection (level 7 vs 6). IP67 is rated for dust-tight and temporary immersion (up to 1 m), while IP16 provides > 50 mm — back of hand and powerful water jets (12.5 mm nozzle).
IP67 is dust-tight and withstands temporary immersion in water up to 1 meter for 30 minutes. The go-to rating for outdoor and rugged devices that may be briefly submerged.
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 (IP67 vs IP16)
Solid protection
IP67
Level 6 — Dust-Tight
IP16
Level 1 — > 50 mm — Back of Hand
IP67 provides "Dust-Tight" (level 6), while IP16 provides "> 50 mm — Back of Hand" (level 1). IP67 is 5 levels higher.
Liquid protection
IP67
Level 7 — Temporary Immersion (up to 1 m)
IP16
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP67 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP16 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP67 provides 1 level more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP67 offers higher overall protection than IP16. Choose IP67 for harsher environments; IP16 may suffice for milder conditions and can be more cost-effective.
