IP69K: The IP69K is the IP Code (Ingress Protection Rating) for the classification of devices subjected to high‐pressure jet, high‐temperature wash‐down applications. The International Standard ISO 29653 and DIN 40050‐9 extend the IP ratings to the maximum protection mode IP69K. Tests: The tests for the verification of IP69K require submitting the device to high‐pressure water jets, at four different angle positions (0°, 30°, 60, 90°) for a minimum of 30 seconds on each position. The distance between the nozzle and the test specimen is only 100 to 150 mm at 100 bars and a temperature of 80°C. The specimens are located on a rotary test table turning at 5 R.P.M. for making a high load of minimum 15l/min on all directions.
