Guideline reference

Dear All,

Does anyone have any reference to an official document (ICH, USP, EP etc) that states that temperature monitoring of any equipment that requires it, has to be a round number i.e 20 degrees or does it need to be defined as 20.0?

Or is this something that the site SOP should capture?


General requirement: 25 deg C plus or minus 2 deg C, Relative humidity: Not more than 60%RH
