11. Component Testing
Please inform TE-VSC regarding any components to be installed in the vacuum systems as soon as possible, after ECR approval.
All the components need to be submitted for acceptance test to the VSC-BVO section before 01/12/2016.
If any component that is due to be installed in the machine during the EYETS is submitted for vacuum acceptance test after this date, the activity has to be taken into account in the general installation planning.
In this case our resources will be divided between the machine activities and the lab activities, with possible delays on the installation.
