This Standard defines uniform Quality and Technical requirements relative to metallic parts marking performed in using "Data Matrix symbology" (2D) coding used within the aerospace industry. The ISO 16022 specifies general requirements (data characters encodation, error correction rules, decoding algorithm, etc.). In addition to this specification, part Identification with such coding is subject to the following requirements to ensure electronic reading (scanning) ability of the symbol. The marking processes covered by this standard are as follows: Dot Peening Laser Marking Electro-Chem Etching Further marking processes will be included if required. Unless specified otherwise in the contractual business relationship, the company responsible for the design of the part shall determine the location of the Data Matrix Marking. Symbol position should allow illumination from all sides for readability.

This SAE Aerospace Standard (AS) defines uniform Quality and Technical requirements relative to metallic parts marking performed in using "Data Matrix symbology" used within the aerospace industry. The ISO/IEC 16022 specifies general requirements (data character encodation, error correction rules, decoding algorithm, etc.). In addition to ISO/IEC 16022 specification, part identification with such symbology is subject to the following requirements to ensure electronic reading of the symbol. The marking processes covered by this standard are as follows: Dot Peening Laser Electro-Chemical Etching Further marking processes will be included if required. This standard does not specify information to be encoded. Unless specified otherwise in the contractual business relationship, the company responsible for the design of the part shall determine the location of the Data Matrix Marking. Symbol position should allow optimum illumination from all sides for readability.
