The methodology identifies analyses that follow the chemical changes which control the deterioration of physical properties of materials during photoageing. The main procedure is based on IR spectroscopy analysis and is described in the standard. In addition, UV spectroscopy is used for monitoring the behaviour of some additives and to identify the origin of discoloration in polymeric materials (degradation of pigments and colorants, or polymer yellowing).
Examples of applications of this methodology are given in an annex as guidance for the interpretation of the results.
