Standard Method of Test for Comparative Qualitative Corrosion Characterization of Steel Bars Used for Concrete Reinforcement (Linear Polarization Resistance and Potentiodynamic Polarization Tests)
standard by American Association of State and Highway Transportation Officials, 2017



AASHTO T 373M/T 373-17 describes procedures to evaluate the comparative qualitative corrosionperformance of uncoated Corrosion Resistant Reinforcing (CRR) M 334M/M 334 alloy steel barsto those of M 31M/M 31 or other selected reference bars, utilizing electrochemical polarizationresistance and potentiodynamic polarization measurements in various test solutions. The testmethods evaluate the corrosion performance of the uncoated CRR bars as a function of (1) pH ofthe environment and (2) concentration of chloride ions, in particular the [Cl?]/[OH?] thresholdratio.
