This Aerospace Standard (AS) documents the requirements for NADCAP industry consensus-based accreditation programs. Under these programs a supplier of an accredited product, process, or service is authorized by NADCAP to use the programs mark (a mark of conformity) and a certificate to indicate that the accredited product, process, or service is in compliance with applicable standards and/or specifications. The procedures in this document are based on ISO/IEC Guides for third-party certification, registration, and accreditation programs where these guides do not violate United States laws. The adoption of these guides allows Internationa harmonization of requirements for certification, registration, and accreditation. Covered within this document and referenced documents are the operations of the NADCAP Management Council with its committees and task groups, NADCAP staff and field personnel, procedures for conducting audits, awarding accreditation, and continuing surveillance of suppliers. Supported recognized consensus standards and/or audit criteria define requirements for supplier compliance with NADCAP requirements for each individual porduct, process, or service to be accredited.
