Ingress Protection – Dripping Water Tests (IPX1 and IPX2)

Ingress protection testing tests the level of protection an enclosure provides against intrusions. One such set of ingress protection tests is called the dripping water test. These tests are numbered IPX1 or IPX2. 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 dripping water ingress protection test, would always be either a 1 or a 2.

Below is a brief description of the two types of dripping water tests included in ingress protection testing from IEC 60529.

IPX1 Testing:

  • Defined as dripping water with vertically falling drops.
  • The requirement is that the equipment under test (EUT), shall experience no harmful effects from the dripping water.
  • The test details include a test duration of 10 minutes and a water equivalent to 1mm of rainfall per minute.

IPX2 Testing:

  • Defined as dripping water when tilted up to 15°.
  • The requirement is that the EUT shall experience no harmful effects when the enclosure is tilted at an angle up to 15° from its normal position and exposed to dripping water.
  • The test details include a test duration of 10 minutes and a water equivalent to 3mm rainfall per minute.

For a complete list of all of the possible IPX1 and IPX2 ingress protection code combinations, as detailed in IEC 60529, please see the chart at the bottom of this page.

What sets Keystone Compliance’s IPX1 and IPX2 dripping 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.
