Abstrakt: The paper is devoted by simulation of conditions of sun radiation in correlation with real loading in operational conditions of selected polymeric materials. In the second the paper is devoted by simulation of temperature conditions of loading again in correlation with temperature loading in real operational conditions of selected polymeric materials. There are tested sensitivity of selected analytic methods in connection on running processes of ageing of polymeric materials for evaluation of initial of radiation ageing and temperature ageing with possibilities of prediction of evolution of running changing of properties and behaviour of evaluated materials. There are tested method x-ray fluorescence analysis and parameters of this method are optimized for increasing sensitivity for evaluation initial changing of properties and behaviour of tested materials on the base the first results. Indentation methods are used for analysis of changing of mechanical properties and behaviour namely static nanoindentation and scratch nanoindentation. These methods are optimized on the base the first results too. There are used more possibilities for control of indentation tests by the use different modes of measurements namely simple and cyclic measurement, setting different rate of loading and using different type of indentors for realization of measurements.
