What does IP69K mean?
IP69K is an internationally accepted protection level certification standard, which is mainly used to evaluate the dust and water resistance of equipment in extreme environments.
"IP" stands for: Protection.
"6" indicates the highest dust protection level.
"9" represents: Waterproof level.
"K" stands for: Compliant with German/international automotive standards, applicable to DIN or ISO automotive industry standards, emphasizing dynamic flushing and long-term reliability.
The difference between IP69 and IP69K
| Contrast items | IP69 |
IP69K |
Difference analysis |
| Dustproof test conditions | Completely dustproof (IP6X) | Completely dustproof (IP6X) + vacuum tested | IP69K requires additional vacuum testing (pressure difference ≤ 2kPa) to ensure that there is no dust residue on the housing |
| Waterproof test conditions | high pressure water column | 80℃ high temperature water column, 80~100Bar pressure, 4-direction spray | IP69K fixed water temperature 80℃, water pressure 80~100Bar, and needs to spray from 0°, 30°, 60°, 90° in four directions, total duration ≥ 2 minutes |
| Supplementary differences | No "K" mark, only meets basic protection requirements | With "K" logo, in compliance with German/international automotive standards | "K" stands for DIN or ISO automotive industry standards, emphasizing dynamic flushing and long-term reliability |
IP69K Application Areas
New energy vehicles: key components such as high-voltage wiring harnesses and battery pack seals;
Industrial equipment: food processing machinery, medical equipment, and other scenarios that require high-frequency cleaning.
