PPF vs. PPAP
PPF ist die Abkürzung für
Production process and product release
Difference between PPF and PPAP
How the PPF procedure also, is PPAP (Production Part Approval Process) a procedure for ensuring quality, but the PPAP procedure is based on the American working group for supplier quality requirements (AIAG = Automotive Industry Action Group). Whereas PPF is based on the German automotive industry (VDA Volume 2).

Documentation of the procedures
Bei der Übergabe der zur Überprüfung gelieferten Teile, müssen Dokumente übergeben werden, die alle wichtigen Informationen, Tests und Anforderungen beinhalten.
- Bei der AIAG spricht man von PSW (Part Submission Warrant).
- Bei der VDA von EMPB (Initial sample inspection report).
VDA Band 2 (2020): Annäherung des PPF-Verfahrens an das PPAP-Verfahren
In the 6th edition of VDA Volume 2, the template stages are dropped in order to better meet the requirements and individual wishes of the customer. Another innovation from VDA Volume 2 is the approximation of the PPF procedure to the PPAP procedure of the AIAG. In our Blog entry we describe the innovations and highlights of the 6th edition.
