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.
