IP64 vs IP19K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP64 and IP19K are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 6 vs 1) and liquid protection (level 4 vs 9K). IP64 is rated for dust-tight and splashing water (all directions), while IP19K provides > 50 mm — back of hand and high-pressure, high-temp water jets.
IP64 is dust-tight and resists splashing water from any direction. A solid outdoor-covered rating combining complete dust exclusion with splash tolerance, sitting between IP65 (jets) and IP54 (dust-protected).
Under IEC 60529, IP19K specifies protection against solid objects larger than 50 mm and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. It is an IEC 60529 ingress protection code combining first-digit (solid) level 1 with second-digit (liquid) level 9K.

The exact difference (IP64 vs IP19K)
Solid protection
IP64
Level 6 — Dust-Tight
IP19K
Level 1 — > 50 mm — Back of Hand
IP64 provides "Dust-Tight" (level 6), while IP19K provides "> 50 mm — Back of Hand" (level 1). IP64 is 5 levels higher.
Liquid protection
IP64
Level 4 — Splashing Water (all directions)
IP19K
Level 9 — High-Pressure, High-Temp Water Jets
IP64 handles 50–100 kPa (Splashing Water (all directions)), while IP19K handles 8–10 MPa (High-Pressure, High-Temp Water Jets). IP19K provides 5 levels more liquid protection.

Recommendation
IP64 and IP19K offer comparable overall protection; choose based on the specific protection dimension (dust vs. water) that matters most for your application.
