Dear K. Boonsong,
Feedback for your question:
Question 2: The O-ring had been changed from TRU or not and need to confirm ==> Klaus
Answer: O-ring Changing should be done from our side (AMC)
Additional supporting document (Purpose for reuse VCV from TRU in case of O-ring changing):
Note: Unfortunately, we can't use this risk assessment to support the current situation. Because we don't change the o-ring.
If you have any questions or any suggestions, please don't hesitate to let me know.
Thank you in advance for your support.
