1.1 General This standard specifies requirements for DPRV to establish common product/service requirements for use at all levels of the supply chain. This standard shall apply when an organization elects to delegate product release verification by contractual flow down to their supplier (reference EN 9100 and EN 9110 standards); to perform product acceptance on their behalf. The delegating organization shall use this standard as the baseline for establishing a DPRV process, although they may include additional contract requirements to meet their specific needs. 1.2 Application This standard is intended for use by organizations that produce and/or provide aviation, space, and defence products, including organizations providing maintenance, spare parts, materials, and services. It is emphasized that the requirements specified in this standard are complementary, not alternative, to contractual and applicable statutory and regulatory requirements. Should there be a conflict between the requirements of this standard and applicable contractual, statutory, or regulatory requirements, the latter shall take precedence.
