This European Standard establishes requirements for performing and documenting APQP and PPAP. APQP begins with conceptual product needs and extends through product definition, production planning, product and process validation (i. e. PPAP), product use, and post-delivery service. This European Standard integrates and collaborates with the requirements of the EN 9100, EN 9102, EN 9103 and EN 9110 standards. The requirements specified in this European Standard are complementary (not alternative) to contractual and applicable statutory and regulatory requirements. Should there be a conflict between the requirements of this European Standard and applicable statutory or regulatory requirements, the latter shall take precedence.
