Issue

What is the difference between IP69 and IP69K?

 

Resolution

The most general distinction is that IP69 testing is for equipment, like control panels or electrical equipment that is installed in areas that get washed (pharmaceutical manufacturing, industrial food packaging), and IP69K is for equipment installed on road vehicles. And the IP69K testing is meant to validate that the equipment installed in road vehicles can withstand very 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.

Here are the most important points:

  1. IP69 is testing from an IEC standard and is for electrical equipment while IP69K is testing from an ISO standard and is for electrical equipment mounted on road vehicles.
  2. IP69 testing requires that the FORCE of a water jet is measured during the water test while IP69K testing requires that the PRESSURE of the water jet is measured during the water test.
  3. The distance of the water jet nozzle can be up to 50 mm further away for the IP69 water test (200 mm) as compared to the IP69K water test (max distance is 150 mm).
  4. Frequently DIN 40050-9 is indicated as a rationale for requiring IP69K testing. DIN 40050-9 is not an active standard.

 

Cause

Customer wants to know if NXM36 can be installed in an application where IP69K is required
