GB/T 39482.1-2023 is the first part of the electrochemistry Impedance Spectroscopy (EIS) standard for painted and unpainted metal specimens, which mainly focuses on terms and definitions. This part provides accurate explanations of the professional terms involved in EIS testing, such as Impedance, phase angle, equivalent circuit, etc., and clarifies the relevant definition boundaries. By uniformly standardizing these terms, the ambiguity of understanding in the industry is eliminated. It lays the foundation for the accurate implementation of EIS test methods, Data analysis and result interpretation in subsequent parts of the standard, and helps researchers and inspectors to communicate and operate smoothly in the research and testing of metal protective coatings.
