Abstract:
Corrosion is not exclusive to exterior structures and components. There are interior environments that can also be severely corrosive. The article provides a summary of some common interior conditions and structures that may be susceptible to corrosion, gives designers some concepts to consider when evaluating corrosivity of interior components, and offers general guidelines for mitigation measures.
