Tunnel Validation

During Tunnel validation temperature monitoing is to be done from the infeed zone to the cooling zone.Is that sufficent to stimulate the total day activity of running during the actual process?

tunnel validation has to be clubbed with the vial washing validation or separate validation is required?

what is the science of using the stainless steel Biological indicator for tunnel validation.

what is ur purpose, simulating the total filling process or only tunnel sterilization. If it is tunnel sterilization, no need to simulate the tunnel sterilization. Perform temperature monitoring as u mentioned and include filter velocity and intergrity in the programme.
