Hello, I am looking for some industry standard guidance on retention time for ISO 13485 certified systems. We manufacture single use IVDDs for professional use only. We are working on defining our retention times, because as a start-up, we have so far just kept all records forever, and we are to the point that we need to define disposal times. The specific types of records that I am questioning our retention time are: Corrective Action/Preventive Action Requests Customer Feedback Internal Audit Reports Management Review Meeting Records Supplier Evaluations Supplier approval documentation Production cleaning records Obsolete procedure and specification document revisions Training records Any DHR records are to be kept for the lifetime of the product (defined as the shelf-life) plus 3 years. Any industry guidance people can give me (with reasoning if needed) on retention times for the above listed documents is appreciated! Thanks in advance! I'm so happy to have this forum reincarnate of the Cove! Thank you to all who run it and contribute! It is an invaluable resource for those of us new to the industry (like me)!
