ASTM RR:G01-1027 PDF Download

ASTM RR:G01-1027 standard is a specification that outlines procedures for measuring the corrosion potentials of uncoated reinforcing steel in concrete. These measurements are important for assessing the likelihood of corrosion occurring in reinforced concrete structures, as well as determining the effectiveness of corrosion protection measures.

The standard was developed based on an interlaboratory study conducted by six different laboratories. These laboratories tested five concrete samples to establish a precision statement for the ASTM C876 test method. The purpose of this study was to determine the level of agreement and variability among different laboratories when performing the corrosion potential measurements.

The ASTM RR:G01-1027 standard provides detailed guidelines on specimen preparation, test equipment, and testing procedures. It specifies the use of saturated calcium hydroxide solution as an electrolyte and outlines the steps for measuring and recording the corrosion potentials. The standard also includes recommendations for data analysis and reporting.
