IEC 61360-2:20 12根据IEC 61360-1和ISO 13584-42中给出的范围提供了数据的正式模型。它为这种数据的计算机敏感表示和交换提供了一种手段，允许实现处理根据任一标准传递的数据的字典系统。第三版取消并取代了2002年出版的第二版及其修正案1（2003）。这是一次技术修订。它包括以下重大技术变化: -表征类和分类类之间的概念分离； -引入对类和属性的值约束； -为数据类型添加各种新的子类型，包括rational_type； -改进计量单位的表示。 根据IEC指南108，它具有水平标准的地位。

IEC 61360-2:2012 provides a formal model for data according to the scope as given in IEC 61360-1 and ISO 13584-42. It provides a means for the computer-sensible representation and exchange of such data, allowing for the implementation of dictionary systems dealing with data delivered according to either of the standards. This third edition cancels and replaces the second edition published in 2002, and its Amendment 1 (2003). It is a technical revision. It includes the following significant technical changes:
- separation of concepts between characterization class and categorization class;
- introduction of value constraints on classes and properties;
- addition of various new subtypes for data types, including rational_type;
- improvement on the representation of unit of measurement.
It has the status of a horizontal standard in accordance with IEC Guide 108.
