METHOD AND APPARATUS FOR DIAGNOSING DETERIORATION

摘要

PURPOSE: To diagnose the life of a metal material without requiring an exposure test of a metal material over a long period of time. CONSTITUTION: The corrosive loss in weight to the number of exposure days in the atmosphere of a metal material is formulated as a function of an environmental evaluation point showing a degree of the harmfulness of atmospheric environment and the life of the metal material is diagnosed on the basis of the corrossive loss in weight calculated from the function.
