I bet you’re wondering if there’s a difference between IP69 and IP69K? The answer is yes and it’s an important distinction.

The most general distinction is that IP69 testing is for equipment, (control panels, electrical equipment etc.) that is installed in areas that are washed (pharmaceutical manufacturing, industrial food packaging, etc.). IP69K is for equipment installed on road vehicles. IP69K testing is meant to validate that equipment installed in road vehicles can withstand severe wash-downs with pressure washers.

IP69 is the IP (ingress protection) code for a very high level of protection as indicated in IEC 60529 – Degrees of protection provided by enclosures (IP code).

IP69K is the IP code for a very high level of protection as indicated in ISO 20653 – Road Vehicles – Degress of protection (IP code) – Protection of electrical equipment against foreign objects, water and access.
