Dose response relations of PP

In the partly funded collaborative project ""ViPQuali1"" the ageing of a polymer part was numerical simulated on the basis of geographical, geometrical, environmental, material data, and time. Starting point was the numerical computer aided construction and design of the part. This construction is then exposed virtual in a box (Instrument Panel Box) to the environmental conditions described by the geographical data of the site and the calculated environmental conditions depending on day time, meteorological, material and geometrical data. The change in material properties (ageing) of the part at any point of the surface was estimated by using the dose-response-functions for these properties and statistical evaluations for the environmental conditions. For the validation of the numerical simulation parallel measurements on real parts were done in IP/DP boxes in Arizona and in the artificial investigations in the laboratories. The dose-response-functions for the polypropylene specimen were additional developed in an exposure program with Xenon Text Beta equipment. In the paper the work program for the Xenon Test will be presented.
