In this study, a computer-controlled, automated artificial test apparatus was developed that permitted subjecting sealant products to a deterioration process that was similar to that of outdoor exposure. Three kinds of sealant product were selected. Outdoor environmental data was collected over a one year period that included, joint movement-of the automated outdoor exposure test rig and specific weathering factors such as the temperature of sealant, quantity of solar radiation and rainfall. As a result, the movement, temperature, total radiation and wetting conditions of the indoor test were nominally the same as those extracted from the outdoor test with the exception of the wavelength distribution for solar radiation. Comparing results of the deterioration of sealant after one year of testing, the indoor test apparatus proved to offer a high degree of correlation to results obtained in the outdoor test for sealant products MS-1 and MS-2. The results suggest that the development of the proposed indoor test using the automated artificial test apparatus appears promising given the degree to which results can reproduce those obtained from ageing sealant products outdoors.
