Product No: JL-IWJ-010
The JL-IWJ-010 Cold Water Shock Test Chamber offers both Ice Water Splash and Ice Water Submersion test modes, supporting independent testing of either mode. It simulates the real-world environment of ice water splashing or submersion into heating systems and components when driving a car on wet winter roads. This equipment can reproduce typical failure modes such as mechanical cracking and sealing failure caused by differences in the coefficients of thermal expansion of materials. It is suitable for raw materials and components in the electronics, electrical engineering, appliance and plastics industries, conducting reliability tests on cold resistance, heat resistance, ice water splash resistance, and ice water submersion resistance. Utilizing a precise temperature and humidity control and flow regulation system, it ensures stable and controllable test conditions, providing a suitable environmental simulation for the reliability testing of various raw materials and components.
