Determination of long-term radiation ageing in polymers - Techniques for monitoring diffusion-limited oxidation1 Scope This part of IEC TS 61244, which is a technical specification, reviews experimental techniques to quantitatively monitor the effects when oxygen is present during ageing of polymers in various environments including temperature, radiation or ultraviolet. Inhomogenous ageing effects caused by diffusion limited oxidation are often encountered and provide theoretical equations to estimate their importance. These effects make it difficult to

if the application of a calculation method as engineering tool to predict real-world scenarios leads to validate results
