Retention of tooling records

For example a part is manufactured continuously and the expected product life is 10 years. does that mean 10+1 year records of tools needs to be maintained?

Answer:

The records for the tools need to be maintained during the active time of production which means that to be kept as long as the product is being produced plus one calendar year, not product lifetime plus one calendar year. Considering the changes in products this time probably wouldn't take 10 years, but you also need to consider customer and legal requiremnets when it comes to retention of this type of documents.
