AASHTO T 375M/T 375-17 is a standard method of testing that provides guidelines for identifying iron-based alloy steel bars used in concrete reinforcement or dowels. The primary tool used for this identification process is a handheld X-ray fluorescence (XRF) spectrometer. This method enables the detection and analysis of the chemical composition of the steel bars, which is crucial for ensuring their suitability and quality in concrete structures.

The standard outlines the specific procedure to be followed when using the XRF spectrometer for the identification process. It includes instructions on sample preparation, calibration of the instrument, and the method of acquiring and analyzing the data. The goal is to accurately determine the presence and concentration of different elements in the steel bars, such as carbon, manganese, sulfur, phosphorus, and others.

By using this standard method, engineers, contractors, and inspectors can effectively verify the composition of iron-based alloy steel bars, ensuring compliance with specifications and standards for concrete reinforcement. This information helps to guarantee the durability and strength of concrete structures, preventing premature failure and ensuring the safety of infrastructure projects.
