What is ISO 23706 about?
ISO 23706 describes a test method to determine the activation energy (Ea) of photochemical degradation reactions in accelerated weathering tests according to the Arrhenius model in the most comprehensive manner.
NOTE 1- Different property changes, for example, yellowing and surface cracking of one material can have different activation energies.
NOTE 2- ISO 23706 , the activation energy is considered as temperature independent for the selected temperature range.
