Very interesting topic! I have been auditing and been audited to AS9100 for over six years now and never had an issue with raw materials until recently. One contract auditor this year decided to take it to a level that I am not comfortable with. He looks at raw material as anything that has a test report that can be validated. In other words, Loctite, conformal coat, RTV, roll solder, solder paste, flux, alcohol, etc..
I my opinion this does not make sense as most if not all of these products are third party tested by the manufacture with objective evidence readily available.
Good news is I hear this requirement is being removed from rev (C). I would think instead of removing they could have simply clarified the requirement. I can understand the need in certain circumstances.
