本文件定义了扩展矩形数据矩阵（DMRE）的符号要求。它规定了DMRE代码符号特征、数据字符编码、符号格式、尺寸和打印质量要求、纠错规则、解码算法和用户可选择的应用参数。 它适用于任何印刷或标记技术产生的所有DMRE代码符号。 本文件不包括原始数据矩阵代码大小，但ISO/IEC 16022使用相同的矩阵布局、解码和纠错算法定义了原始数据矩阵代码大小。

This document defines the requirements for the symbology known as extended rectangular data matrix (DMRE). It specifies the DMRE code symbology characteristics, data character encodation, symbol formats, dimensions and print quality requirements, error correction rules, decoding algorithm, and user-selectable application parameters. It applies to all DMRE code symbols produced by any printing or marking technology. Original data matrix code sizes are not covered by this document but defined in ISO/IEC 16022 using the same matrix placement, decoding and error correction algorithm.
