本标准定义了与航空、航天和国防工业中使用“数据矩阵符号”进行的金属零件标记相关的统一质量和技术要求。ISO/IEC 16022规定了一般要求（例如，数据字符编码、纠错规则、解码算法）。除ISO/IEC 16022规范外，具有此类符号的零件标识应符合本标准的要求，以确保符号的电子读取。本标准涵盖的标记工艺如下:-点喷丸-激光-电化学蚀刻-如果需要，将包括进一步的标记工艺。除非合同业务关系中另有规定，否则负责零件设计的公司应确定数据矩阵标记的位置。 符号位置应允许从各个侧面进行最佳照明，以确保可读性。本标准未规定要编码的信息。

This standard defines uniform quality and technical requirements relative to metallic parts marking performed using "data matrix symbology" within the aviation, space, and defense industry. ISO/IEC 16022 specifies general requirements (e.g., data character encodation, error correction rules, decoding algorithm). In addition to ISO/IEC 16022 specification, part identification with such symbology is subject to the requirements in this standard to ensure electronic reading of the symbol.The marking processes covered by this standard are as follows:- Dot Peening- Laser- Electro-Chemical EtchingFurther 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 optimum illumination from all sides for readability.This standard does not specify information to be encoded.
