METHOD OF PREDICTING DURABILITY OF COATED METAL MATERIAL

摘要

Method of predicting the durability of a coated metal material after the lapse of a desired number of years by an approximate formula of y=f(x) representing the complete graph obtained by plotting executed exposure test data and artificial acceleration test data in a coordinate system with years on the x-axis and the measured values of the property to be predicted on the y-axis to predict the durability of the properties selected in response to the utility and environmental conditions of the coated metal material by the step of obtaining a solution to the approximate formula in accordance with both sets of test data.
