ABSTRACT |
The aim of this study was to establish a test method with improved reliability and reproducibility for the
accelerated weathering test of automotive interior materials. For this purpose, this study measured the spectral power
distribution (SPD) of the glass used in actual vehicles in the oceanic climate region of South Korea (Seosan) and in the desert
climate region of North America (California Proving Ground). In addition, the SPD was measured according to the position
of automotive interior parts, and cumulative light intensity was calculated using the curve fitting method. Results showed that
the measured light intensity varied according to the position of interior parts because of numerous variables such as the type
of glass, angle of sunlight, and frames of vehicles. We investigated the cumulative light intensity of the solar glass used in this
study and the glass of other manufacturers, and the obtained data were incorporated into a data base (DB). Understanding the
optical characteristics of filters is important accelerated weathering tests (Xenon). Therefore, we compared the SPD and
cumulative light intensity of each filter combination and actual automotive glass to confirm the suitability of the filters for
weathering tests. |
