IEC 61406-2:20 24补充了IEC 61406-1，为其中数据元素以标准化语法和语义编码在结构化标识链接字符串内的那些情况提供了附加要求。 此外，本文件涵盖了唯一性与产品类型/型号或批次/批次相关的情况。默认假设是标识链接标识唯一对象，例如唯一序列化的产品、资产、人员或包，除非另有标识。

IEC 61406-2:2024 complements IEC 61406-1 by providing additional requirements for those cases where data elements are encoded within the Structured Identification Link string with standardized syntax and semantics.
In addition, this document covers cases where the uniqueness relates to product types/models or lots/batches. The default assumption is that the Identification Link identifies unique objects such as unique serialized products, assets, persons or packages, unless otherwise identified.
