Conditions of tests • Tedlar • Foil of ~ 2x0.25 m2 in outgassing box • Surface-to-flow ratio: 3 h/cm • ALICE surface-to-flow: 5 h/cm • ARALDIT 2013 • Four glass slides painted on both sides • Surface-to-flow ratio: 0.01 h/cm ____________________________________________ • No gas recirculation • No heating of sample
Conclusions • The set-up and the sensitivity of our gas mixture to 'everything' makes it difficult to perform controlled ageing tests, • although any significant degradation would be detected • No ageing effect can be attributed to the materials tested so far
