  2. Carboys were filled with 10 or 20 liters (nominal maximum volume) with tap water and sealed to the recommended torque of 8Nm for cryogenic applications. Net weight of the filled carboys was approximately 10.7 kg and 20.7 kg .
  3. Carboys were put in an ultra-low deep freezer at -80°C and stored for 2 days until the carboys stabilized at -80°C.
  4. Subsequently, all 5 carboys were dropped from a height of 533mm (21in.) onto a flat concrete surface;
    • from its base;
    • from one of its four sides;
    • from its closure.
    • 533mm height provides assurance level 1 for this container weight.
  1. Subsequently, carboys  were dropped from a height of 11OOmm (43in.) on to a flat concrete surface;
    • from its base;
    • from one of its four sides;
    • from its closure.
  1. Failure is defined as a visually detectable leak after test. The containers were allowed to thaw in order to check for leaks.
 
All tested containers passed at both heights. There were some minor scratches but no loss of integrity.
