IP16 vs IPX8
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP16 and IPX8 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 0) and liquid protection (level 6 vs 8). IP16 is rated for > 50 mm — back of hand and powerful water jets (12.5 mm nozzle), while IPX8 provides no protection and continuous immersion (manufacturer-specified).
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.
IPX8 protects against continuous immersion under manufacturer-specified conditions (depth and duration), with solid protection not specified. The standard for submersible consumer electronics.

The exact difference (IP16 vs IPX8)
Solid protection
IP16
Level 1 — > 50 mm — Back of Hand
IPX8
Level 0 — No Protection
IP16 provides "> 50 mm — Back of Hand" (level 1), while IPX8 provides "No Protection" (level 0). IP16 is 1 level higher.
Liquid protection
IP16
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IPX8
Level 8 — Continuous Immersion (manufacturer-specified)
IP16 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IPX8 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IPX8 provides 2 levels more liquid protection.

Recommendation
IPX8 offers higher overall protection than IP16. Choose IPX8 for harsher environments; IP16 may suffice for milder conditions and can be more cost-effective.
