I've been trying to get a copy of TL9000 but the company won't pay for it. We have a customer that wants to know why we're not certified to that rather than ISO 9001...so far corporate has said they didn't feel it was necessary. After talking with our MR, I find that he's never seen the standard either!
I had hoped to be of help in this forum and wanted to learn about it myself, but that doesn't look likely anymore.
Best regards to all..
