1.1 Application This standard defines the common nonconformance data definition and documentation that must be exchanged between an internal or external supplier or sub-tier supplier and the customer when informing about a nonconformity requiring formal decision. The requirements are applicable - partly or totally - when reporting a product nonconformity to the owner or operator as user of the end item (e.g. engine, aircraft, spacecraft, helicopter etc.), if specified by contract. Reporting of nonconformance data, either electronically or conventionally on paper, is subject to the terms and conditions of the contract. This also includes, where applicable, data access under export control regulations. 1.2 Purpose The process of exchanging coordinating and approving nonconformance data via waiver/concession or product quality escape varies with the multiple relationships and agreements among all parties concerned. The information provided by this standard forms an architecture for submitting and managing data that allows for concise and accurate communication using various methods. The main objective of this standard is to provide the definition of a data set that can be integrated into any form of communication (e.g., electronic data interchange, submission of conventional paper forms).
