NACE SP0308-2018

This NACE International standard practice provides testing procedures and investigative techniques for the evaluation of conventionally reinforced concrete structures. The investigation and evaluation techniques described in this standard focus on degradation resulting from corrosion of the reinforcing steel. These techniques range from simple visual inspections that identify rust staining, cracks, and delamination to physical and chemical inspection methods, which use hammer rebound, ultrasonic testing, electrical resistance, chemical analyses, or electrochemical potential and corrosion rate measurements.

This standard is intended for use by corrosion specialists, civil engineers, and structural engineers involved with evaluating corrosion of reinforcing steel in concrete. It also may be useful to owners of reinforced concrete structures whose service life may be affected by reinforcing steel corrosion. It includes commentary for screening corrosion control methods that might be considered for restoration of the reinforced concrete structure being evaluated.
