Amund,
As you continue looking at this, I believe that you will find that the IP testing is an “enclosure” test. The compliance criteria is not actually so much whether or not the influx of dust or water affects your product. What will matter is if you passed the definition of the enclosure rating that you want.

We’re doing an IPX6 test (high pressure water jet) according to IEC60529. Some water enter the unit, but drain holes make their job. Only plastic enclose in that area anyway. But, a few drops are discovered on a plastic material switch inside the unit and also some drops on two connection poles on the swicth. We have failed on this test because (according to the test lab) in the long term, creepage currents can cause the two poles to be shorted and thereafter a incorrect function will appear. Is it likely to believe that such creepage currents can occur, when the two poles are placed 10mm from each other and the voltage supply is 3.3VDC? b.r.
