Dear Forum!
I have a very simple question regarding 
Validation of depyrogenisation tunnel.
What is current approach to penetration studies:
1. three runs of thermocouples and endotoxins at begin (filing of tunnel), middle (tunnel full) and end (last row of ampoules during empting) - one load
Or
2. three runs of load (in that case where thermocouples and endotoxins) - three loads

Thanks in advance
Chris
