NACE SP21461-2020

This standard provides the investigator, corrosion specialist, engineer, or owner a framework for evaluating the corrosion condition of a steel frame building beyond simple visual inspection and basic sounding techniques. Evaluation techniques that identify general and localized corrosion of masonry-clad steel frame buildings are provided.

This standard is intended for use by corrosion specialists, historic architects, structural engineers, and exterior building envelope consultants involved with evaluating corrosion of steel frame buildings and the subsequent effect on the masonry cladding. It also may be useful to owners of historic buildings whose service life may be affected by steel frame corrosion.
