The Sterilizing &
Depyrogenating Tunnel when operated with Empty Chamber is capable of producing
the temperature profiles as per the temperature set points set in the PLC of
the equipment. The temperature distribution is uniform throughout the
sterilization period.

the Sterilizing & Depyrogenating Tunnel also start the data logger to
record the actual temperatures within the Sterilizing & Depyrogenating
Tunnel with respect to time.

4.0 RESULT:
The
results obtained after execution of the protocol, will be
presented in the validation report. All results will be compared against
the acceptance criteria. Any deviation failure to meet these specifications
will be duly documented. A deviation indicates variance from the acceptance
criteria however, does not necessarily mean that the qualification as
unacceptable. During execution of this protocol, if any deviation is noticed,
the person executing the protocol initiates a deviation report and provides the
detail description of the deviation. Investigation may be performed to identify root cause for the deviations or failures and corrective action will be taken to minimize such deviations or failures in the
future.
5.0 CONCLUSION:
Conclusion
will be drawn after compilation and evaluation of result.

dear sir,
ReplyDeletei want to know about air velocity of HEPA in sterilization zone in sterilization and depyrozination tunnel it 150-200 FPM. it obey which guideline?
hope you reply me soon
regards,
sohel
What about bracketing approach in tunnel
