Ingress Protection: High-Temperature and High-Pressure Water Jets Tests (IPX9)
Ingress protection testing tests the level of protection an enclosure provides against intrusions. One such set of ingress protection tests involves exposing the equipment under test (EUT), to high-pressure and high-temperature water jets. These tests are numbered IPX9. The first digit, represented by the “X”, ranges from 0 to 6 and specifies the protection from solid particles. The second digit, in the case of the high-pressure and high temperature water jets ingress protection test, would always be a 9.
