Evaluating the Reliability of Predictions of First-Year Corrosion Losses of Structural Metals Calculated Using Dose-Response Functions for Territories with Different Categories of Atmospheric Corrosion Aggressiveness

To predict $$K_{1}^{{{\text{pr}}}}$$ values, the dose-response functions (DRFs) presented in the ISO 9223:2012(E) standard were used, both new and universal ones. This work is based on experimental data of the corrosion losses of St3, Zn, Cu, and Al for the first year of exposure ( $$K_{1}^{{\exp }}$$ ) and calculated by the DRF values ​​of corrosion losses for the first year ( $$K_{1}^{{{\text{pr}}}}$$ ) for the test sites conducted in the framework of international UN/ECE and Russian programs, as well as the MICAT project. For these places, the necessary atmospheric aggressiveness parameters for DRF were taken into account. The categories of atmospheric corrosion activity are adopted in accordance with ISO 9223:2012(E) standard.
