+AMD1:2003 CSV 电气元件的标准数据元素类型及相关分类方案 第1部分：定义 原理和方法

[中文适用范围]： 为电工系统从基本组件到子组件和完整系统的所有元素的特征属性（数据元素类型）的清晰和明确的定义提供了坚实的基础。尽管最初的构想是为电气/电子部件的信息交换提供基础，但也可以用于原始概念之外的领域，例如部件组装以及电工系统和子系统。规定建立分类层次结构并将适用的相关属性分配给如此建立的每个类，以便充分描述属于该类的对象的特征。还对分类中使用的术语的定义做出了规定。通过定义的信息结构促进描述电工系统的数据交换，以便以计算机感知的形式交换信息。与 IEC 61360 的这一部分密切相关的是 IEC 61360-2。这部分包含信息模型，使用EXPRESS建模语言。使用此信息模型允许使用 ISO 10303-21 中定义的 STEP 物理文件格式在不同系统之间交换字典信息。根据 IEC 指南 108，它具有水平标准的地位。该合并版本由第二版 (2002 年) 及其修正案 1 (2003 年) 组成。因此，无需对本出版物进行修订。 [外文原描述]： Provides a firm basis for the clear and unambiguous definition of characteristic properties (data element types) of all elements of electrotechnical systems from basic components to subassemblies and full systems. Although originally conceived in the context of providing a basis for the exchange of information on electric/electronic components, may be used in areas outside the original conception such as assemblies of components and electrotechnical systems and subsystems. Provides for establishing a classification hierarchy and the allocation of applicable and relevant properties to each of the classes so established in order to describe fully the characteristics of objects belonging to that class. Provision is also made for definition of the terms used in classification. Facilitates the exchange of data describing electrotechnical systems through a defined structure for the information to be exchanged in a computer-sensible form. Closely associated with this part of IEC 61360 is IEC 61360-2. This part contains the information model, using the EXPRESS modelling language. Use of this information model allows dictionary information to be exchanged between different systems using the STEP Physical File Format as defined in ISO 10303-21. It has the status of a horizontal standard in accordance with IEC Guide 108. This consolidated version consists of the second edition (2002) and its amendment 1 (2003). Therefore, no need to order amendment in addition to this publication.
