📝 Foreword / 前言 ai_extracted

This standard is identical to ISO/IEC 16390:1999 *Information technology — Automatic identification and data capture techniques — Bar code symbology specification — Interleaved 2 of 5*, and revises GB/T 16829-1997 *Interleaved 2 of 5 bar code*. To facilitate understanding and retrieval in Chinese, the Chinese standard name is set as "信息技术自动识别与数据采集技术条码码制规范交插二五条码". To better suit Chinese reading habits, the positions of Appendix B and Appendix D in the original standard have been swapped. Compared with GB/T 16829-1997, the main changes in this standard are as follows: — The standard name has been changed from "Interleaved 2 of 5 bar code" to "信息技术自动识别与数据采集技术条码码制规范交插二五条码"; — The decoding algorithm has been replaced by the reference decoding algorithm in ISO/IEC 15416, instead of the traditional decoding algorithm in the original standard; — The quality inspection of bar codes has been replaced by the comprehensive quality grade assessment of bar code symbols in ISO/IEC 15416, instead of the traditional quality inspection method in the original standard; — The calculation method for the check character of the bar code symbol has been added; — Appendix A "Additional features", Appendix B "Examples of application-defined parameters", Appendix C "Symbology identifier", and Appendix D "Application guidelines for Interleaved 2 of 5 bar code" have been added. Appendices A, B, C, and D of this standard are informative appendices. This standard is proposed and managed by the Article Numbering Center of China. This standard is drafted by: Article Numbering Center of China. Main drafters of this standard: Wen Xiangyang, Han Jiming, Zhang Chenghai, Luo Qiuke. This is the first revision. This standard replaces GB/T 16829-1997 *Interleaved 2 of 5 bar code*. GB/T 16829-2003/ISO/IEC 16390:1999 Introduction Bar code technology is an identification technology based on coding graphics composed of bars and spaces with specified dimensions. There are many methods for encoding information into well-known bar code symbols, and the rules for converting characters into bar and space graphics, along with other characteristic rules, constitute what is known as a symbology specification. Interleaved 2 of 5 is one of these symbologies. In the past, many organizations developed and published various symbology specifications, leading to contradictions among certain symbologies. Manufacturers of bar code equipment and users of bar code technology require open, standard symbology specifications for reference during equipment development and application standardization.

本标准等同采用ISO/IEC 16390:1999《信息技术— 自动识别与数据采集技术— 条码码制规范— 交插二五》，对GB/T 16829-1997《交插二五条码》进行修订。为方便中文的理解与检索，中文的标准名称定为“信息技术自动识别与数据采集技术条码码制规范交插二五条码”。为更适合中文阅读习惯，将原标准中的附录B与附录D的位置进行了交换本标准与GB/T 16829-1997相比主要变化如下: — 标准名称由“交插二五条码”改为“信息技术自动识别与数据采集技术条码码制规范交插二五条码”; — 译码算法以ISO/IEC 15416中的参考译码算法代替了原标准的传统译码算法; — 条码质量的检测以ISO/IEC 15416中的条码符号综合质量等级评定代替了原标准的传统质量检测方法; — 增加了条码符号校验符的计算方法; — 增加了附录A“附加特征”、附录B` ‘应用规定参数的示例”、附录C` ‘码制标识符”和附录D` ‘交插二五条码应用指南”口本标准的附录A、附录B、附录C和附录D是资料性附录。本标准由中国物品编码中心提出并归口。本标准起草单位:中国物品编码中心。本标准主要起草人:文向阳、韩继明、张成海、罗秋科本标准为第一次修订。本标准代替GB/T 16829-1997《交插二五条码》。 GB/T 16829- 2003/ISO/IEC 16390;1999 引言条码技术是基于规定了尺寸的条和空组成的编码图形的标识技术。有许多方法可以将信息编码成为众所周知的条码符号，而将字符转换为条、空图形的规则与其他特性的规则就是我们所知的码制规范。交插二五条码就是这些码制之一。过去由许多组织开发并发表了多种码制规范，导致某些码制相矛盾的情况出现。条码设备的制造商和条码技术的用户需要公开的、标准的码制规范，以便他们在设备开发与应用标准时能够及时查阅 GB/T 16829- 2003/ISO/IEC 16390:1999 信息技术自动识别与数据采集技术条码码制规范交插二五条码
