Accelerated Corrosion Test

Accelerated corrosion testing is used to simulate the conditions that a manufacturer's or supplier's product will be exposed to during actual service. Since a product's performance is often linked to its service environment, it is crucial to consider various aspects of inclement weather and corrosive environmental conditions during the manufacturing process.

Laboratory exposure testing provides manufacturers and suppliers with an advanced understanding of the limitations of the components used in their products before these components are purchased or integrated into larger systems or final products. This forward-thinking approach not only reduces the time, energy, and costs associated with inferior products but also minimizes the risk of losing market position and customers due to poor product performance. In essence, accelerated corrosion testing induces corrosion and failure in a relatively short period compared to natural corrosion processes. This enables decision-makers to make informed choices, such as tweaking designs, using alternative materials, or discontinuing suppliers of inferior products.

Accelerated corrosion testing involves subjecting test components to conditions that are more severe than normal service conditions, resulting in shorter lifespans than would typically be observed. For example, results obtained at higher temperatures (i.e., accelerated conditions) can be extrapolated to room temperature (i.e., normal conditions) to estimate the product's lifespan under normal operating conditions.

Since the primary goal of accelerated testing is to compress the natural degradation process into a reasonably short period, it is essential that the simulated conditions have a direct correlation to normal operating conditions. Additionally, it is highly desirable to preserve failed devices in a condition that allows for careful examination to determine the root causes of failure.
