Splash water test chamber is suitable for ice water splash test of products. It is simulating winter when ice water splashes onto heating systems or components while driving on wet roads. The failure mode is mechanical cracking of the material or seal failure due to different thermal expansion coefficients. Splash water test chambers are reliability testing equipment for various electronic, electrical, electrical, plastic and other raw materials and devices for cold resistance, heat resistance, ice water splash resistance test, ice water immersion resistance test and quality control engineering.
The main function of the ice water testing machine is to perform ice water impact test on the main components of passenger cars, buses, tractors, motorcycles and other vehicles. The ice water shock test chamber mainly simulates the thermal shock caused by ice water for products used in the splashed area of the vehicle. Simulates icy water splashing onto hot systems/components while driving on watery roads in winter. The ice water shock test chamber is a reliability test equipment for various electronic, electrical, electrical, plastic and other raw materials and devices to perform cold resistance, heat resistance, ice water splash resistance test, ice water immersion resistance test and quality control engineering.

| Splash Water Test: the DUT is heated to T for the respective holding time. Afterwards cold splash water is applied to the DUT for 3 s. The DUT is splashed with water from one direction while being in as-installed position. If the DUT can be splashed from various directions in the vehicle, then these directions must be taken into account. If this is the case, a new DUT must be used for each direction. The width of the splash directed at the DUT must be greated than the width of the DUT. If the DUT of considerable size are splahed that prove too big for one nozzle, several nozzles must be arranged in a row to produce a line of splash impact on the DUT. | |

| Then spray the DUT with ice water for 3 seconds. If the DUT is splashed in only one direction on the vehicle, spray water only in that direction of the installation location. | |
| If the equipment is exposed to water splashing in multiple directions on the vehicle, these directions shall be stated and a new DUT shall be tested in each direction. | |
| The width of the splash is controlled to always be greater than the width of the DUT. | |
| If the size of the DUT receiving the splash is much larger than a single sprinkler head, multiple sprinklers should be arranged to splash water on the DUT in a row. | |

Splash water test chamber
is mainly suitable for ice water impact test on cars or auto parts, because the engine will heat up when the car is driving on the road, and if it is in the cold winter or north, there may be rain and snow weather, which will cause the road to freeze. Or thick snow, when the car is exposed to such a sudden drop in temperature, it will lead to flameout or even an accident. Therefore, in order to avoid such a situation, the car needs to do high temperature and high pressure rain test and ice water impact during the manufacturing process to increase the safety performance of the car. Generally, IPX9 test chamber is used for high temperature rain test, while ice water shock test chamber is used for ice and heat resistance test.| The splash water test chamber produced by Wewon Environmental Chambers Co., Ltd. is suitable for the ice water splash test of the product. | Equipment Features |
