Ingress Protection: Dust Protected and Dust Tight (IP5X & IP6X)

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 dust. These tests are numbered IP5X and IP6X. The first digit, in the case of dust protected, would always be a 5, and in the case of dust tight, would always be a 6. The first digit, represented by the “X”, ranges from 0 to 9 and specifies the protection from liquid.

Below is a brief description of IPX5 and IPX6 testing as detailed in IEC 60529:

IP5X Dust Protected Testing:

  • Defined as the ingress of dust is not entirely prevented.
  • However, dust must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment.

IP6X Dust Tight Testing:

  • Defined as no ingress of dust.

For a complete list of all of the possible IP5X and IP6X ingress protection code combinations from IEC 60529, please see the chart at the bottom of this page.

What sets Keystone Compliance’s IP5X dust protected and IP6X dust tight 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.
