Abstract

In order to quantify weatherabily of polymeric building materials, reference materials(RM), polyethylene, polycarbonate and poly(ethylene terephthalate), are exposed every month in Sapporo, Choshi and Miyakojima for 2 years. Carbonyl index or ultraviolet absorbance of reference materials are analyzed by multiple regression analysis and Koike & Tanaka's model, based on solar ultraviolet radiation, ambient temperature and relative humidity. Citing meteorological data provided by Japan Meteorological Agency, carbonyl index or ultraviolet absorbance rate are estimated and are plotted on maps. These values shall be adopted_as a new concept of exposure stage.
