What is IP69K ?

The IP69K level was established in 1993. The Electronic Control Units had became more common on trucks and were able to withstand high pressure water often necessary to clean trucks. A new test (§9) was introduced in the DIN40050 standard “Road vehicles - degrees of protection (IP-code) - protection against foreign objects - water and contact - electrical equipment

A summary of the test conditions is shown opposite.


Today, this cleaning method has been adopted by many other industries. For example in the food-processing industry, IP69K has almost becomes a must. IP69K is also required in the pharmaceutical and petrochemical industries.


Advantages of high pressure wash down:

Compared to a hose down cleaning process:

less water for the same cleaning result

less detergent used

For protection against dust, ice and sand, please use APEM sealing boots
