we are registered to QS9000TE. Does anyone have any input regarding 18.104.22.168 concerning the 20 hour dry run. Do these run-offs have to be a continouous 20 hour run? There has been a recent debate internally, that machines could be shut down during the shift change and started the next morning. Has anyone ran into similar difficulties surrounding the run-off requirements established in 4.2. Any suggestions would be appreciated.
