What is a IPX9K Test Machine?

Our customers, like Allen Johns, Sr. Reliability Engineer, have praised the RD-800C model for its effectiveness in product development, stating that it has been "very useful in helping us develop new outdoor products." The machine's automated turntable, high-pressure nozzles, and live-function testing capabilities allow comprehensive evaluation of even complex electronic systems, ensuring that products perform reliably in real-world outdoor environments.

LIB's IPX9K Test Machine provides a versatile, high-precision solution for validating water ingress resistance and dust protection. Designed for industries including automotive, defense, outdoor electronics, and industrial machinery, the system supports IPX1–IPX9K testing and ensures reproducible results compliant with IEC 60529, ISO 20653, DIN 40050-9, and JIS D0203 standards. With integrated turntables, automated controls, and closed-loop water circulation, it guarantees precise, repeatable, and safe testing while reducing water consumption and labor.

The IPX9K Test Machine simulates extreme water exposure with precision. Its operation combines high-pressure, high-temperature water jets, adjustable specimen rotation, and controlled flow to replicate real-world challenges:

Water Spray Mechanics: Four stainless-steel nozzles spray water sequentially at 0°, 30°, 60°, and 90°, delivering water at +88 °C and 8000–10000 kPa. Each nozzle sprays for 30 seconds per position, ensuring every surface of the specimen is exposed to the maximum force.

Turntable Functionality: The chamber's automated turntable supports specimens up to 50 kg and rotates at 5 ± 1 r/min. The height is adjustable from 200–400 mm, and a tilt of up to 15° allows testing of inclined or irregularly shaped items. Small components are secured with custom fixtures to prevent displacement under high water pressure.

Water Flow Control: The chamber uses a PID-controlled electromagnetic flow system, maintaining water flow between 14–16 L/min with ±0.01 kPa pressure deviation. A closed-loop system recirculates water through built-in filtration, ensuring stable pressure and temperature while conserving water.

Live-Function Testing: Specimens can remain energized during testing via a waterproof power supply, allowing engineers to observe real-time operational performance under extreme wet conditions.

This system's design ensures that even prolonged high-pressure exposure does not compromise sample placement or measurement accuracy, providing consistent and repeatable results across IPX1–IPX9K testing cycles.

IEC 60529 defines the requirements for Ingress Protection (IP) testing. For IPX9K, the standard specifies the highest level of water resistance:

Pressure and Flow: Water jets must reach 8000–10000 kPa, delivered at a flow rate of 14–16 L/min. Nozzles are positioned at 0°, 30°, 60°, and 90° to ensure multi-angle coverage.

Temperature: Water temperature must be elevated up to +80 °C or higher (LIB achieves +88 °C), simulating hot water jetting or industrial wash-down conditions.

Duration and Exposure: Each nozzle sprays for 30 seconds per angle, with continuous rotation of the test platform to ensure uniform exposure.

Specimen Handling: Objects are mounted securely to prevent movement, and tests include both powered and non-powered conditions to replicate real-world operation.

Integration with Dust Protection: IPX9K testing often complements IP6X dust-tightness testing (dust-free ingress), verifying full environmental protection.

These requirements are further referenced in ISO 20653 (road vehicle equipment), DIN 40050-9 (automotive applications), IEC 60068-2-68 (environmental testing of components under dust and water), and ASTM standards. Compliance ensures products withstand industrial cleaning, rainstorms, and outdoor exposure without failure.

Testing automotive or industrial lighting requires precise simulation of extreme water conditions while ensuring the device remains operational. The LIB IPX9K Test Machine enables full IPX1–IPX9K testing with automated, reproducible procedures for luminaires, ensuring reliability and standards compliance.

Step 1: Mount the Test Specimen
Place the luminaire securely on the adjustable turntable or suspend smaller items using the overhead beam. The turntable supports loads up to 50 kg, adjustable height from 200–400 mm, and tilt up to 15° for multi-angle exposure.

LIB Advantage: Custom fixtures prevent small components from moving during high-pressure water exposure, ensuring accurate and repeatable results. The adjustable platform accommodates various luminaire sizes and orientations, improving operational flexibility.

Step 2: Set Water and Test Parameters
Use the 7-inch color touchscreen to configure water temperature (ambient to +88 °C), pressure (8,000–10,000 kPa), nozzle angles (0°, 30°, 60°, 90°), spray duration (30 seconds per nozzle), and turntable rotation (5 ± 1 r/min).

LIB Advantage: PID-controlled electromagnetic flow ensures ±0.01 kPa pressure stability and flow rate 14–16 L/min, maintaining precise, reproducible conditions. One-touch mode switching allows easy transition between IPX levels without manual reconfiguration, reducing operator error.

Step 3: Execute Water Spray Testing
Activate the water spray sequence. The automated turntable rotates the specimen while sequential nozzles spray high-pressure, high-temperature water, ensuring full surface exposure.

LIB Advantage: The closed-loop water circulation system maintains consistent pressure and temperature while recycling water, lowering consumption by up to 80%. Integrated filtration prevents nozzle clogging, ensuring uniform spray and reliable test results.

Step 4: Live-Function Testing
If the luminaire is powered, the built-in waterproof power supply allows real-time operation during testing. Engineers can verify functionality under extreme wet conditions.

LIB Advantage: Live-function monitoring ensures that lighting and electronics continue to operate safely under test conditions, replicating real-world use and validating product performance.

Step 5: Post-Test Inspection and Data Logging
Observe the luminaire through the wiper-equipped viewing window with internal LED lighting. Check for water ingress, operational integrity, and seal performance. Automatically log all test parameters and generate ISO/IEC-compliant reports.

LIB Advantage: LED-lit window and wiper system allow uninterrupted visual inspection. The controller stores all test data for traceability, reducing manual reporting and facilitating compliance with IEC 60529, ISO 20653, and DIN 40050-9 standards.

Step 6: Prepare for Successive Tests
After completion, the water is automatically drained and recirculated for the next test cycle, minimizing downtime and maintaining consistent conditions.

LIB Advantage: Automated water recovery and recirculation simplify lab workflow, enabling high-throughput testing with reduced labor and resource consumption.

The system allows full customization of nozzle types, spray angles, flow rates, immersion depths, and platform sizes. Laboratories can tailor the setup to comply with specific standards such as IEC 60529, ISO 20653, DIN 40050-9, or to accommodate oversized or irregularly shaped products. Recently, we have been developing bespoke walk-in IP waterproof test chambers for automotive applications, featuring dozens of IPX5 and IPX6 nozzles. LIB remains committed to delivering fully customized IP testing solutions to meet the unique needs of each laboratory.
