There are 4 documents that make up the TS series (the "4-pack" as opposed to the "7-pack" for QS); 1) ISO/TS 16949 - Quality Systems - Automotive Suppliers - Particular requirements for the application of ISO 9001:1994, 2) ISO/TS 16949 Customer-Specific Manual (DaimlerChrysler and Ford only)(GM's is available off of the internet), 3) ISO/TS 16949 Checklist Manual, and 4) ISO/TS 16949 Automotive Certification Scheme - Rules for achieving IATF recognition. Of the 4, only the standard itself and the checklist are available for purchase from AIAG, the official source(I think) in the US. When I call AIAG, I am informed that the customer specific manual and the certification scheme are not released/published and there is no date available for when they will be published. Does anybody know what the registrars that are performing assessments are using in lieu of the two unreleased/unpublished documents? My understanding is that the TS certificates need to be very specific and include the actual customer specific requirements that the system has been audited and certified to. If the TS customer specifics for Ford and DC are not published, what was used? My guess is that when they are published they probably won't be much, if any, different than those contained in QS.
