Immersion testing is a method used to evaluate the performance and reliability of products, particularly in the electronics and automotive industries. This testing involves placing a device or component in a controlled environment, often involving water or other fluids, to simulate real-world conditions. The goal is to identify any potential failures or weaknesses that may arise when the product is exposed to such environments. During immersion testing, various factors such as temperature, pressure, and duration are carefully monitored. This helps engineers and designers understand how well the product can withstand challenging conditions, ensuring that it meets safety and quality standards before it reaches consumers.
