IPX9 High-Temperature and High-Pressure Water Jets Tests
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.
Protection against close-range high pressure, high
temperature spray downs.
EUT shall experience no harmful effects from the
high-pressure and high-temperature water spray.
Test details include:
Smaller specimens rotate slowly on a turntable, with 4
specific angles.
Larger specimens to be mounted upright, no turntable
required, tested freehand for at least three minutes at distance of 0.15–0.2 m.
The test time is 30 seconds in each of the four angles, for
two minutes of total testing.
A specific nozzle must be used, with water volume should be
14–16 liters per minute.
Water pressure to be 8–10 MPa (80–100 bar) at distance of
0.10–0.15 meters.
Water temperature should be 80 °C.
