Ever wondered how your car sensors or outdoor electronics survive high-pressure cleaning or harsh weather conditions? In today’s technology-driven world, durability is not a luxury—it’s a necessity. For automotive components, industrial control devices, and outdoor electronics, reliable water ingress protection determines long-term performance and safety.
That’s where IPX9K waterproof testing becomes indispensable. Recognized as the highest level of waterproof protection in the IP rating system, IPX9K testing verifies a product’s ability to resist high-pressure, high-temperature water jets from multiple angles.
LIB Industry, a global manufacturer of advanced environmental test systems, provides precision-engineered IPX9K test equipment built in strict accordance with ISO 20653, IEC 60529, and DIN 40050-9 standards. These systems deliver accurate, repeatable, and traceable results for research, certification, and production testing.
The IPX9K rating was introduced under ISO 20653—primarily for road vehicles—and complements the more general IEC 60529 IP classification. It defines a test that exposes the sample to close-range, high-temperature water jets under extreme pressure.
This test simulates real-world conditions such as industrial wash-downs, automatic car washes, or outdoor operation during heavy rain. A sample passes the IPX9K test if no water ingress or functional failure occurs after exposure to high-pressure jets at elevated temperature.
While IPX5 and IPX6 simulate medium-pressure rain or spray, IPX9K increases the stress level significantly—up to ten times higher pressure and water heated to 80 °C. This makes it essential for applications requiring extreme durability and sealing performance.
During testing, the specimen is placed on a rotating turntable that ensures every side receives equal exposure. Four precision nozzles spray water at 0°, 30°, 60°, and 90° angles while maintaining constant temperature and pressure.
- Water temperature: 80 °C ± 5 °C
- Spray pressure: 8–10 MPa (80–100 bar)
- Exposure duration: 30 seconds to several minutes per angle
- Turntable speed: up to 5 rpm
- Control: Touchscreen PLC with monitoring, logging, and fault alarms
This process accurately simulates high-pressure cleaning or heavy rainfall, ensuring enclosures, connectors, and seals perform reliably under realistic conditions.
LIB Industry combines precision engineering with long-term reliability to deliver world-class performance.
- High-Pressure Nozzle System – Four stainless-steel spray nozzles ensure consistent pressure distribution.
- Temperature Control Accuracy ±0.5 °C – Maintains stable test conditions across extended cycles.
- PLC Controller – Customizable programs with automatic data recording.
- Servo-Controlled Water Pressure Regulation – Stability within ±1%.
- SUS 304 Stainless-Steel Structure – Corrosion-resistant and durable.
- Optional Integrated Drying Module – Reduces post-test cycle time by 30%.
All components comply with ISO 20653, IEC 60529, and DIN 40050-9 standards.
To meet the diverse waterproof and dustproof testing demands of modern products, LIB Industry not only supplies IPX9K high-pressure water jet test equipment, but also a full series of IP waterproof and dust test systems covering IPX1 to IPX9K, as well as IP5X–IP6X dust chambers and MIL-STD sand and dust chambers.
These solutions enable engineers and manufacturers to perform complete IP protection verification in one laboratory setup — from light rain simulation to high-pressure water jets and desert dust exposure.
