《生产件批准程序》（PPAP）第四版（英文版） PRODUCTION PART APPROVAL PROCESS (PPAP) FOREWORD TO THE THIRD EDITION The Production Part Approval Process (PPAP) Third Edition was issued to incorporate a number of revisions which include: ?? Use of “auditable” language and a format consistent with QS-9000 to support third party auditing; ?? A reordering of the PPAP requirements aligned with the typical process flow; ?? Revision of “Preliminary Process Capability Requirements”, now called “Initial Process Studies”, to provide for the use of either Cpk or Ppk, depending on the amount and type of data available, consistent with our Statistical Process Control reference manual; ?? Clarification of when customer notification and/or submission is required; ?? The prior IASG QS-9000 Sanctioned Interpretations specific to PPAP; ?? A Truck OEM-Specific Instructions; ?? Requirements for bulk material, including a Bulk Material-Specific Appendix; ?? Tire Industry-Specific Appendix; ?? An enhanced glossary of terms. The actual changes of the previous PPAP text are minimal, and evolutionary. While the additions have increased the size of the document, they provide greater clarification of PPAP requirements and allow application of PPAP requirements to a broader community of users. Current training modules sanctioned by DaimlerChrysler, Ford and General Motors have been revised to incorporate these changes. Acknowledgments are due to the DaimlerChrysler, Ford and GM Supplier Quality Requirements Task Force (Hank Gryn, Dan Reid and Steve Walsh), Michael Schons from DaimlerChrysler, Carol Myers and Rudy Pomper from General Motors, Paul Norkevicius from Ford, Patricia Messenger from the Chemical Manufacturers Association, Joseph Muscedere from the AIAG Truck and Heavy Equipment Group, and Steve Butcher from the Rubber Manufacturers Association. The PPAP Third Edition obsoletes the Second Edition effective February 1, 72000 unless otherwise specified by your customer. September, 1999 i February, 1995 FOREW
