Why UL Suzhou Laboratory Selected a Customized Rain Test Room
Waterproof testing for certification laboratories is different from routine factory inspection. The equipment must support different test levels, flow rates, spray angles, pressure conditions and sample positioning requirements. It must also help operators reduce manual adjustment and maintain repeatable test conditions.
For this project, KingPo supplied a complete integrated Rain Test Room rather than a single waterproof test device. The system combines drip testing, oscillating tube testing, spray testing, water jet testing, immersion testing, NEMA 4 spraying and UL rain/spray testing into one controlled test environment.
This configuration helps UL Suzhou Laboratory perform multiple water ingress protection tests more efficiently while maintaining stable and traceable test conditions.
Standards and Test Coverage
The Rain Test Room was designed according to waterproof testing requirements related to IEC 60529, GB/T 4208, UL 50E and UL 1598. It supports IP code waterproof testing, NEMA 4 water spray testing and UL rain/spray test applications.
| Test Level / Standard | Test Function |
|---|---|
| IPX1 / IPX2 | Vertical dripping water test |
| IPX3 / IPX4 | Oscillating tube rain test and hand-held spray test |
| IPX5 / IPX6 | Water jet and powerful water jet test |
| IPX7 | Temporary immersion test |
| NEMA 4 | Water spray protection test |
| UL Rain/Spray | Rain and spray testing for UL-related applications |
This wide test coverage makes the system suitable for certification laboratories, quality inspection centers, electrical manufacturers, enclosure manufacturers, lighting product manufacturers and industrial control equipment suppliers.

Technical Highlights
Integrated IPX1–IPX7 Waterproof Testing
The system supports multiple waterproof test levels in one integrated room. It reduces the need for separate test setups and helps laboratories manage different test methods within a unified control system.
Digital Flow Control for Stable Testing
The intelligent water supply system uses digital flow monitoring and variable-frequency control. Operators can set the required flow rate directly through the touch screen. This helps improve flow stability and test repeatability.
Servo-Driven Oscillating Tube
For IPX3 and IPX4 testing, the oscillating tube is driven by a servo motor. Swing angle, swing speed and test duration can be set through the control interface. This reduces manual mechanical adjustment and improves operation consistency.
PLC + Touch Screen Operation
The Rain Test Room uses a PLC and touch screen control system. Operators can set flow rate, oscillating angle, tube speed, test time and other parameters from the interface. This design supports standardized laboratory operation and easier training.
Anti-Blocking Design
The vertical drip test device and oscillating tube test device are designed with compressed-air blow-dry functionality. After testing, residual water can be removed from the drip needles and tube holes, helping reduce blockage risk and improve long-term equipment reliability.
Rotating and Tilting Sample Table
The system includes a rotating and tilting turntable. The turntable helps expose samples to water from different directions and supports more flexible waterproof test positioning.
Remote Control and Data Storage
The system supports remote operation, data reading, data storage and automatic shutdown time setting. These functions help laboratories improve test management and maintain better operational traceability.
Laboratory-Oriented Engineering Value
For a certification laboratory such as UL Suzhou Laboratory, the value of a Rain Test Room is not only in performing waterproof tests. The equipment must also support repeatability, maintainability, operator safety and efficient daily workflow.
KingPo designed this system with laboratory use in mind. The integrated configuration reduces repeated setup work. The digital control system helps operators quickly select test parameters. The anti-blocking and maintenance-oriented design helps reduce downtime. The remote control and data storage functions support modern laboratory management.
Installation, Training and Service Support
KingPo provided installation, commissioning and operator training for this project. The training covered equipment principles, operating procedures, maintenance methods and emergency handling.
The project also included after-sales service, software upgrade support and long-term maintenance support. These service capabilities are important for laboratories where equipment availability directly affects testing schedules and project delivery.
Why This Successful Case Matters
The successful delivery of this Rain Test Room to UL Suzhou Laboratory shows KingPo’s ability to support high-standard certification laboratory projects. The project also demonstrates KingPo’s experience in customized waterproof test systems for IEC, GB, UL and NEMA-related testing applications.
For laboratories and manufacturers that need waterproof test equipment for IPX1–IPX7, NEMA 4 and UL rain/spray applications, this case provides a practical reference for integrated test room design, digital control and laboratory-oriented system configuration.
