IP19K
Last updated: Aug 9, 2026Under 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.

What IP19K means
The IP code IP19K is part of the IEC 60529 standard for ingress protection. The first characteristic numeral, 1, indicates the level of protection against solid objects and access to hazardous parts. The second numeral, 9K, indicates the level of protection against the ingress of water. Together, these digits describe exactly what an enclosure rated IP19K can withstand.
For solid protection, the digit 1 means the enclosure is > 50 mm — back of hand. Protected against access to hazardous parts with the back of a hand. Protected against solid foreign objects of 50 mm diameter and greater. The test method is access probe (50 mm sphere) shall not fully penetrate and shall have adequate clearance from hazardous parts.
For liquid protection, the digit 9K means the enclosure resists high-pressure, high-temp water jets. Protection against high-pressure and high-temperature water jets. Water projected in powerful jets against the enclosure from any direction shall have no harmful effects. Often designated IPx9K. The test procedure is fan-shaped 80° nozzle at 14–16 l/min, 8–10 mpa pressure, water temperature 80 °c; enclosure on turntable hit at 0°, 30°, 60°, 90° for 30 seconds each.
IP19K is a valid IEC 60529 combination. When specifying IP19K for a project, confirm the rating certificate from the manufacturer and consider that seals degrade over time with temperature cycling, UV exposure, and chemical contact.
