EDA-IMA is an EDA-project where the impact of ageing on the low sensitivity properties of different energetic materials that are included in IM is studied.The aim of this project is to develop surveillance methods for these energetic materials if shown to be needed and suggest a methodology to predict for how long time the initial IMproperties of the munition is assessed to be maintained. The work reported on here is the results from work package 2 (WP 2) where the ageing properties of different low sensitivity energetic materials have been studied. FOI has chosen to study the ageing behaviour of the two LOVA propellants NL007 and NL008 based on RDX and CAB. This report contains results from different analyses of propellant samples subjected to forced ageing at a simulated age between 0 and 20 years. The resultats from these analyses indicate that the propellant grains become brittle at ageing and might split at high pressure burning.
