IPX3 and IPX4 waterproof tests can be carried out with this hand-held device. It is equipment complementary to the IPX 3 & 4 Test Chamber, as It is suitable for big specimens which can’t be tested by the IPX Test chamber.
The spray nozzle is made of brass. There are a total of 121 holes (0.5 mm in diameter) distributed on the surface of the showerhead orderly. One is located at the center of the cambered surface, which is surrounded by 6 circles of holes, including 12 holes per circle in the inner two circles at a distance of 30° pitch, and 24 holes per circle in the outer four circles at a distance of 15° pitch. The moving shield is formed from aluminum. The test piece is placed 300-500mm away from the nozzle during the test. The counterbalanced shield is in place for IPX 3 test, but it must be removed from the spray nozzle to allow the enclosure to be sprayed from all possible directions when conducting the IPX4 test. The water pressure is adjusted to a value ranging from 50kPa to 150 kPa to reach the given delivery rate at a constant speed during the test. The test duration is 1 min / m² of the calculated surface area of the enclosure (mounting surface is not included), with a minimum duration of 5 min.
