The main function of the rain test chamber is to test the performance of the equipment during storage, transportation, and use in a rainy climate environment. This equipment is mainly used for simulating electronic and electrical equipment, lamps, cabinets, electrical components, automobiles, motorcycles, and their components
Under rainy weather conditions, the physical and other related performance of the equipment is tested. After testing, the performance of the equipment is determined to meet the requirements through calibration, in order to facilitate the design, improvement, calibration, and factory inspection of the equipment.

4、 Experimental method
IPX5 water spray test
Experimental equipment: The inner diameter of the nozzle’s spray port is 6.3mm
Water pressure: 0-30kpa
Experimental conditions: Keep the distance between the test sample and the water spray nozzle at 2.5-3m, with a water flow rate of 12.5L/min (750L/h);
Test time: Calculated based on the surface area of the tested sample shell, 1 minute per square meter (excluding installation area) for at least 3 minutes.
IPX6 strong water spray test
Experimental equipment: The inner diameter of the nozzle’s spray port is 12.5mm;
Water pressure: 0-300kPa
Experimental conditions: Keep the distance between the test sample and the water spray nozzle at 2.5-3m, with a water flow rate of 100L/min (6000L/h);
Test time: Calculated based on the surface area of the tested sample shell, 1 minute per square meter (excluding installation area) for at least 3 minutes
5、 Structure and Characteristics
The rain test chamber is made of high-quality materials and processed using the most advanced processing equipment currently available in China. The surface of the outer shell is treated with spray coating for a beautiful and smooth appearance. Coordinated color matching, curved design, smooth and natural lines. The inner liner is made of imported high-quality stainless steel plate. The indoor sample racks and other accessories are made of stainless steel or copper materials, with a reasonable design and durability. set up
On the premise of meeting national standards and ensuring stable performance in all aspects, it is more practical and easy to control.
The entire box of the rain test equipment adopts an integral structure, divided into three parts: upper, lower, and right. The upper part is the working room, the lower part is the mechanical room, and the right side is the electrical control cabinet. High quality materials are selected and processed using advanced technology. The inner shell is made of high-quality SUS304 stainless steel plate. The indoor sample rack and other accessories are made of stainless steel material, with a reasonable design and durability.
