The Wewon IPX9K rain test chamber is meticulously engineered to meet and exceed the rigorous protection class requirements outlined in ISO 20653, IEC 60529, and DIN 40 050 standards. Designed for evaluating the waterproof integrity of automotive parts, electronic enclosures, and industrial machinery, this equipment ensures reliable testing under extreme environmental conditions. To accommodate various testing requirements, Wewon provides multiple test room volumes, including 500 liters, 1000 liters, and 1250 liters, offering ample space for different sample sizes and load weights.
Transitioning from the technical specifications to the physical design, the chamber features a robust exterior and interior constructed entirely from premium SUS 304 stainless steel. This high-grade material ensures exceptional durability and resistance to corrosion, even during continuous exposure to high-temperature moisture. Furthermore, the front panel is equipped with an intuitive Siemens 7-inch touch screen controller for precise operation, while the polymethyl methacrylate door with silicone rubber sealing provides a secure, transparent observation window for engineers to monitor the testing process safely.



At the heart of the IPX9K and IP9K testing process is the high-pressure and high-temperature water jet system. The chamber utilizes an imported Italian high-pressure water pump to consistently deliver a water pressure between 8000 Kpa and 10000 Kpa (80 to 100 bar). Hot water, heated to a standard +80℃ and adjustable up to 88℃, is forcefully ejected at a precise flow rate of 14L to 16L per minute. This extreme spray is executed through four precision-calibrated stainless steel fan nozzles, which are strategically positioned on a semicircular arch at 0°,30°,60° and 90° angles relative to the test platform.
To ensure comprehensive exposure to the high-pressure spray, the internal workspace is equipped with a rotating turntable designed to support the test specimen. This SUS#304 stainless steel testing sample shelf rotates at a steady speed of 5 ±1 r.p.m., allowing the water jets to impact the product uniformly from all required directions. During a standard testing procedure, each of the four nozzle angles sprays the sample for exactly 30 seconds, resulting in a total spray testing time of 2 minutes. Following the spray, the water is efficiently managed by the internal thermostatic and backwater double water tank system, ensuring rapid recovery and continuous testing reliability.



While the static design of the Wewon IPX9K rain test chamber highlights its robust SUS304 stainless steel construction and precision-engineered nozzle arch, understanding its real-world performance requires a closer look at its operational dynamics. The physical structural integrity ensures long-lasting resistance against corrosion, but it is the seamless integration of its internal mechanical and electrical systems that guarantees accurate, repeatable waterproof testing for automotive parts and electronic components.
To provide a comprehensive overview of how these core components function in real time, the following video demonstrations delve into the primary operational modules of the equipment. These detailed visual guides will walk you through the efficient water supply mechanism, the intelligent Siemens 7-inch touch screen control system, and the rapid high-temperature water heating process capable of reaching up to 88℃ By exploring these dynamic tutorials, test engineers can fully grasp the advanced capabilities and user-friendly interface that make this testing chamber an industry leader in evaluating waterproof performance reliability.

What is the difference between IPX9K testing and IPX9 testing ? Why add a “K” to the testing standard, IPX9K test specification, and what is the meaning of it ?
IPX9K and IPX9 both come from the waterproof grade standard: ISO 20653-2013 and GB 4208-2017. IPX9 mentioned in GB4208-2017 test standard be introduced is the latest version (Come into force date: Feb, 2018), It can be understood that this standard was introduced by the committee from other standards. So the original test standard came from ISO 20653. IPX4K, IPX6K, IPX9K etc all has “K” term, So we should understand the relationship between the IPX9 and IPX9K.
What is the “K” mean of IPX9K ? “K” refers to the test pressure requirements. IPX9K testing has a 10000 Kpa pressure requirement, and extended to other protection grade, for example, 4K, 6K, actually it keeps the requirement of the water spray pressure. So we should know that “K” mainly mentioned water pressure requirement.
