    Historically, my companies have used a logbook to record when a stability chamber was opened and closed, what the temperature was at the time of opening and closing, the reason for accessing the chamber, who accessed/created an entry in the logbook, and who reviewed the logbook entry. I’ve always been told that this is an industry standard even when there is temperature excursion alarm monitoring, because you need to show the momentary changes in temperature or light exposure that a sample has experienced over time (i.e. a chamber may have never gone out of temp, but over many door openings over time a sample at T=6M may actually be T=5.75M due to disturbances opening and closing the chamber door). Does anyone know if this is a real requirement?
