This document provides harmonized process and documentation requirements for the establishment of Certificates of Conformance (CoC) used to attest the conformity of aviation, space, and defense products. It includes a template and indications about how to complete it.
Requirements for the establishment of Authorised Release Certificates (e.g. EASA Form 1, FAA 8130-3 tag, etc.) by a supplier holding a Production Approval (for new products in production or spares) or Maintenance Approval (for in service repairs and after sales overhaul activities) are not covered by this document as applicable rules are those defined by the Aviation Authorities having granted the Production Approval.
Note: When quoted by the Customer in a contractual requirement, application of this document is mandatory. In other cases its use is recommended but if there is a conflict between the requirements of this standard and customer or applicable statutory or regulatory requirements, the latter shall take precedence.
Rationale: The Aviation Space and Defense organizations (customers) over the world receive products (assemblies, sub-assemblies, parts, material, etc.) that are produced by other organizations (suppliers).
Before using these products to manufacture their own products, or integrating them into their own products, these customers need confirmation from their suppliers that their products comply to the relevant design data and to the purchase order. This is done via an attestation from the supplier called ‘Certificate of Conformance’ (often also called ‘Certificate of Conformity’).
The high number of customers and suppliers may result in a multiplication of Certificate of Conformance templates and associated requirements. The objective of this standard is to provide guidelines about how to issue such Certificate of Conformance, harmonize its content between all suppliers and customers, and provide a consistent process and documentation requirements for verification of aviation, space, and defense products.
