ACCELERATED TEST METHOD FOR QUANTITY OF DIFFUSED ORGANIC SUBSTANCE

摘要

PROBLEM TO BE SOLVED: To provide a means that solves the problems of the conventional technology taking a long time in measurement and efficiently determines the diffusion quantity of an organic substance from a base material at an arbitrary temperature and the age-based attenuation with an acceleration testing method in a short time. SOLUTION: The accelerated test method for the quantity of the diffused organic substance determines the age-based attenuation of the quantity of the organic substance diffused from the base material under an arbitrary temperature. The specimen of a base material is heated at different two points of temperatures or more, and the quantity of a diffused organic substance is measured at different two points of elapsed times t. The quantity Q0of an initial diffused organic substance and an attenuation coefficient k at each temperature are determined from the relationship between the logarithm of the quantity of the diffused organic substance and the elapsed time (t) at each heat temperature. The quantity QT of the initial diffused organic substance at an arbitrary temperature is determined from the relationship between the logarithm of the quantity Q0of the initial diffused organic substance and the inverse number of the heat temperature. An attenuation coefficient kT at an arbitrary temperature is determined from the relationship between the logarithm of the attenuation coefficient k and the inverse number of the heat temperature.
