Re: TS16949 7.4.1.2
David,
Non-IAF members may argue they also operate according to ISO/IEC 17011.
Then your problem is one of evidence.
But as at June 2013 "accreditation to ISO/IEC 17025 or national equivalent is not required", according to Ford Motor Company.
All your customer may require, for now, is evidence that your lab operates to ISO/IEC 17025 or national equivalent.
