ISO 21849:2022 pdf – Aircraft and space — Industrial data — Product identification and traceability.
1 Scope This document specifies the requirements for a product identification and traceability schema for life cycle management of aircraft and space products/parts. It specifies the minimum essential identification information needed for traceability of a product for its life cycle. It also provides the data structures for use with automatic identification technologies that support product/part life cycle data management activities. This document defines a structure and rules for establishing a unique identifier for product/part identification and traceability. The rules and structure provide sufficient options to support various business practices. They provide the minimum amount of standardization required to support interoperability, improved business processes and efficiency across multiple users and applications of machine-readable media technologies. This document also defines and establishes repeatable processes to allow efficient exchange of product data for life cycle product/part traceability, configuration, reliability, maintenance, and product performance management purposes. It specifies the data carriers appropriate for representing the product data in a machine-readable form and associated dimensional and quality parameters. Specific implementation guidelines can be developed by industries or trading partners to employ the principles defined in this document. Although primarily intended for aircraft and space products/parts, this document can be used for other products/parts where desired. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. 3.5 forward oblique stroke / special character used to separate data elements in a data string Note 1 to entry: It is character value 47 in ISO 646. 3.6 in-service product/part product/part for which the original manufacturing process, including application of the identification symbology, has been completed and which is no longer an asset of the manufacturer or portion of the enterprise which owns the manufacturing process 3.7 limited marking space space available on the product/part which is insufficient for a machine-readable symbol and associated human translation representing the essential data for the conformance class (3.2) 3.8 optional data data which is not essential to provide a unique identifier for product/part identification or configuration management/control (part number), but provides supplementary information relative to the product/ part EXAMPLE Traceability data. 3.9 syntax set of rules defining the way in which data is put together with appropriate identifiers, delimiters, separator character(s), and other non-data characters to form messages Note 1 to entry: Syntax is equivalent to grammar in spoken language.
The applicable character set to be used for data encoding shall be the International Reference Version (IRV) of ISO/IEC 646. For direct part marking, Data Matrix (in accordance with ISO/IEC 16022) or QR Code (in accordance with ISO/IEC 18004) shall be used. Direct part marking is considered the most permanent of the machine-readable media techniques for providing life cycle identification of products/parts. NOTE Unless otherwise stated, this document uses the term “matrix symbol” to refer to both Data Matrix and QR Code symbols. For labelling or nameplates, either a matrix symbol, as above, or linear bar codes, namely Code 128 (in accordance with ISO/IEC 15417) or Code 39 (in accordance with ISO/IEC 16388) shall be used. This document makes provision for the use of RFID tags for the representation of both static and dynamic data in a tag affixed to the part, to enable additional operational processes to be performed. This document also provides a legacy product/part identification schema, which is defined in Annex G . 4.2 Product/part identification and traceability decision tree diagram Figure 1 is a decision tree diagram which illustrates — the product/part identification and traceability schema, — the three essential product/part identification data elements, and — the difference between a serialized and a non-serialized product/part.
