Abstract
The following parameters have been used to estimate the reliability of predicted first-year corrosion losses of carbon steel and zinc (\(K_{1}^{{{\text{pr}}}}\)): the standard determination coefficient \(R_{{{\text{st}}}}^{2}\) according to ASTM G 16; statistical indicators such as SMAPE and MAPE; generalized determination coefficients; confidence angle. The experimental data on corrosion losses of carbon steel and zinc (\(K_{1}^{{{\text{exp}}}}\)) and the atmosphere corrosivity parameters were taken from the UN/ECE international program and Russian program. The \(K_{1}^{{{\text{pr}}}}\) values were calculated using various dose-response functions. It is not recommended to use the standard determination coefficient \(R_{{{\text{st}}}}^{2}\) in the y = \(K_{1}^{{{\text{pr}}}},\)x = \(K_{1}^{{{\text{exp}}}}\) coordinates.
