Conditions of tests

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

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
