I had a question in regard to iso rules on a laboratory notebook. For example, when a sample is being weighed out, this gets written down. Is a laboratory notebook mandatory? Can the weights be written down and kept in an excel sheet?
A laboratory can use any medium and format to record technical data as long as the technical information is captured at the time of the activity, it is controlled and retained. The information must be traceable to personnel, equipment and time of activity to meet ISO 17025 clause 7.5 requirements.
