Accelerated Corrosion Testing:  Accelerated corrosion testing is used for various purposes to simulate the conditions that a product will be exposed to in actual service conditions.  As the performance of a product is often linked to the service environment where it is placed, it is of the utmost importance that products are manufactured taking the various aspects of inclement weather and corrosive environmental conditions into consideration.

The use of laboratory exposure testing provides manufactures and suppliers with an advanced understanding of the limitations of the components used in manufactured products prior to the purchase and or inclusion of these products in a larger component of final product.  This forward thinking approach not only limits the time, energy and income spent of inferior products but also limits the risk of losing market position, clientele and customers due to inferior product performance.  In a nutshell, accelerated corrosion testing is used to induce corrosion and failure in a relatively short period of time when compared to corrosion produced as a natural occurrence.  This provides the means for decision makers to tweak, redesign using alternate materials, or eliminate a particular supplier with inferior products altogether.

The investigation of corrosion failures can be very complex, and usually requires multidisciplinary testing and analysis to determine the root cause of failure. The end determination must be able to be made with a high degree of certainty to ensure that proper replacement materials are selected and that the most effective corrosion control methods are used. Experience is surely the most important ingredient to look for when choosing a materials firm to handle your corrosion control and failure analysis needs.
