标准范围

IEC 81346-2:20 19建立了具有定义的对象类别及其相关字母代码的分类方案，主要用于参考名称和通用类型的指定。分类方案适用于所有技术学科和所有工业分支的对象。IEC 81346-2:20 19是一份横向出版物，也旨在供技术委员会根据IEC指南108中规定的原则编写与参考名称相关的出版物时使用。IEC 81346-2:20 19取消并取代了2009年发布的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)已经定义了分类方案的条目类别，以反映被分类对象的“固有功能”；b)定义类别以符合ISO 22274和ISO 704的原则；c)定义了三级分类方案，在某些技术领域为设计者提供了更大的灵活性；d)类由它们的定义来定义，并提供优选的术语。如果需要，提供示例；e)提供了单独的空间分类方案。

IEC 81346-2:2019 establishes classification schemes with defined object classes and their associated letter codes, and is primarily intended for use in reference designations and for designation of generic types.
The classification schemes are applicable for objects in all technical disciplines and all branches of industry.
IEC 81346-2:2019 is a horizontal publication also intended for for use by technical committees in preparation of publications related to reference designations in accordance with the principles laid down in IEC Guide 108.
IEC 81346-2:2019 cancels and replaces the first edition published in 2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) The entry classes of the classification scheme have been defined to reflect the “inherent function” of the object classified;
b) The classes are defined to align with the principles of ISO 22274 and ISO 704;
c) A three-level classification scheme has been defined, which provides a greater flexibility for the designer in some technical fields;
d) Classes are defined by their definition and provided with a preferred term. Examples are provided if needed;
e) A separate classification scheme for spaces has been provided.
