This document 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.
Abstract
Overview
ISO 23706:2020 specifies a laboratory for determining the apparent of photochemical degradation reactions in plastics subjected to accelerated weathering. Using the , the standard defines how to quantify the temperature dependence of specific property changes (for example, yellowing or surface cracking) by comparing exposures at two or more controlled temperatures while keeping all other test parameters constant.
