Production part approval process

Version 4, 1 March 2006Although individual manufacturers have their own particular requirements, the Automotive Industry Action Group (AIAG) has developed a common PPAP standard as part of the Advanced Product Quality Planning (APQP)[1] – and encourages the use of common terminology and standard forms to document project status.

Requests for part approval must therefore be supported in official PPAP format and with documented results when needed.

The documentation on the PPAP package is closely related to the advanced product quality planning process used during the design and development of new vehicles and component systems to reduce the risk of unexpected failure due to errors in design and manufacture.

[4] Additional customer specific requirements may be imposed by particular clients (vehicle manufacturers) and incorporated in the purchasing contracts.

Details of 'customer specific' requirements may be found on the International Automotive Task Force (IATF) website or supplier portals provided by the vehicle manufacturers.

The term ISIR (initial sample inspection report) is being used by German companies like VW and BMW.
