Ingress Protection: Immersion Water Tests (IPX7 and IPX8)
Ingress protection testing tests the level of protection an enclosure provides against intrusions. One such set of ingress protection tests involves immersing the equipment under test (EUT), in water. These tests are numbered IPX7 and IPX8. 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 immersion ingress protection test, would always be a 7 or an 8.
