Ingress Protection: Spraying Water and Splashing Water (IPX3 & IPX4)
Ingress protection testing tests the level of protection an enclosure provides against intrusions. Two such sets of ingress protection tests involve exposing the equipment under test (EUT), to spraying water and splashing water. These tests are numbered IPX3 and IPX4. 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 spraying water, would always be a 3, and in the case of splashing water, would always be a 4.
Below is a brief description of IPX3 and IPX4 testing as detailed in IEC 60529:
IPX3 Spraying Water Testing:
- Defined as water falling as a spray at any angle up to 60°.
- The requirement is that the equipment under test (EUT), shall experience no harmful effects from the water being sprayed against the enclosure from any direction.
- The test details include a test duration of at least five minutes, water volume of 0.7 liters per minute and pressure of 80-100 kN/m².
IPX4 Splashing Water Testing:
- Defined as water splashing against the enclosure from any direction.
- The requirement is that the equipment under test (EUT), shall experience no harmful effects from the water being slashed against the enclosure from any direction.
- The test details include a test duration of at least five minutes, water volume of 10 liters per minute and pressure of 80-100 kN/m².

What sets Keystone Compliance’s IPX3 spraying water and IPX4 splashing water testing apart is our experience in helping manufacturers determine ingress points in their products and also identifying potential solutions. We also have significant expertise in interpreting the standards, which often provides manufacturers with flexibility in determining acceptable amounts of ingress. Just because some liquid may enter an enclosure, does not automatically mean that the unit has not met the requirements. If the unit that requires testing is too large to move, no problem. We have experience completing ingress protection testing at the customer’s facilities.
Why is Keystone Compliance the right IP Code lab to complete your ingress testing? Our customers enjoy our short lead times, ability to explain the process and testing requirements, consultative engineering support when failures occur and affordable pricing. It is what has made us one of the fastest growing companies in the country and most respected test labs in the region.
