Spraying Water and Splashing Water (IPX3 & IPX4)

Two of these ingress protection tests subject the equipment under test (EUT) to water splashing and spraying. These tests have the IPX3 and IPX4 designations. In the case of water spraying, the second digit would always be a 3, while in the case of water splashing, it would always be a 4.

Here are the details of Spraying Water and Splashing Water.

Spraying Water Testing for IPX3:

A spray is defined as water that is falling at any angle up to 60°.
The water being sprayed against the enclosure from any angle must have no negative effects on the equipment under test (EUT).
The test specifications include a minimum five-minute runtime, 0.7 liters of water per minute, and pressures between 80 and 100 kN/m2.

Splashing water testing for IPX4:

Described as water splashing in either direction against the enclosure.
The water being splashed against the enclosure from any direction must have no negative effects on the equipment under test (EUT).
The test specifications include a minimum five-minute runtime, 10 liters of water per minute, and pressures between 80 and 100 kN/m2.
