Production Part Approval Process (PPAP) is the industry standard that ensures engineering design and product specification requirements are met. Through the PPAP guideline, suppliers and customers understand the requirements to obtain part approval of supplier manufactured parts. Applicable to all parts and commodities, application of these principles reduces delays and non-conformances during part approval.
The PPAP process consists of 18 elements that may be required for approval of production level parts. Not all of the elements are required for every submission. There are five generally accepted PPAP submission levels. The PPAP manual contains detailed information, guidelines and sample documents useful for completing the process requirements. The resulting PPAP submission provides the evidence that the supplier has met or exceeded the customer’s requirements and the process is capable of consistently reproducing quality parts.
