Ingress protection (IP) testing is crucial for evaluating how well an enclosure shields its contents from external elements. Among the various IP tests, the IPX9 waterproof test stands out due to its rigorous standards involving high-pressure and high-temperature water jets. This article will delve into the specifics of the IPX9 test as outlined in IEC 60529, ensuring it aligns with Google ranking rules and is search engine optimized.
What is the IPX9 Test?
The IPX9 test is a stringent examination designed to assess an enclosure’s resistance to close-range, high-pressure, and high-temperature water sprays. The “X” in IPX9 signifies that the first digit, which indicates protection against solid particles, can range from 0 to 6. However, for this specific test focusing on water jets, the second digit is always 9.
Detailed Breakdown of the IPX9 Test
Key Features of the IPX9 Test:
- High-Temperature Water Jets:
- The water used in this test is heated to a temperature of 80°C.
- High-Pressure Conditions:
- Water pressure ranges between 8–10 MPa (80–100 bar) at a distance of 0.10–0.15 meters.
- Water Volume:
- The water flow rate should be maintained between 14–16 liters per minute.
- Testing Procedure:
- Smaller specimens are placed on a rotating turntable and exposed to water jets from four specific angles.
- Larger specimens are tested upright without a turntable and are subjected to freehand spraying for at least three minutes at a distance of 0.15–0.2 meters.
- Each angle receives a spray for 30 seconds, totaling two minutes of exposure.
Equipment Used:
To ensure consistency and accuracy, specific nozzles are employed during the IPX9 test. These nozzles are designed to deliver water at the required pressure and temperature.

Comprehensive List of IP Ratings with Water Jet Protection
For those interested in various combinations of ingress protection codes that include high-pressure and high-temperature water jet resistance, here’s a quick reference:
| IP Rating | Protection Against Solid Objects | Protection Against Water |
|---|---|---|
| IP09 | Not Protected | High-pressure and temperature water jets |
| IP19 | Solid object >50 mm | High-pressure and temperature water jets |
| IP29 | Solid object >12.5 mm | High-pressure and temperature water jets |
| IP39 | Solid object >2.5 mm | High-pressure and temperature water jets |
| IP49 | Solid object >1 mm | High-pressure and temperature water jets |
| IP59 | Dust protected | High-pressure and temperature water jets |
| IP69 | Dust tight | High-pressure and temperature water jets |
By understanding these details, manufacturers can better evaluate their products’ durability against extreme conditions, ensuring they meet industry standards.
