IEC 61293:2019规定了用额定值和其他特性标记电气设备的最低要求和一般规则，以便能够正确和安全地选择和安装与任何电力供应相关的电气设备。 本文件的目的是: ？为与任何供电系统有关的特性，如电压、电流、频率和功率的标记提供一般要求，而不受任何限制； ？为技术委员会提供产品电气等级标记的统一方法。 本文件主要供技术委员会在指定与设备、子组件和部件的任何电源相关的额定值的最低标记时使用，但也供产品制造商在标记其产品时使用。本横向标准主要供技术委员会根据IEC指南108中规定的原则编制标准时使用。 技术委员会的职责之一是在适用的情况下，在编写其出版物时利用横向标准。除非相关出版物中特别提及或包含，否则本横向标准的内容将不适用。 IEC 61293:2019取消并取代了1994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)其作为基本安全出版物的地位已被移除，根据IEC指南108，它已成为横向出版物；b)范围扩大到包括本文件对产品制造商的适用性； c)增加了一项规定，即应考虑正常操作期间标记的可见性； d)更详细的要求，其中设备具有给定特性的一组或一系列额定值； e)增加了关于在技术文件中提供标记的要求； f)一些说明已转换为规范性文本； g)更新了规范性参考文献和其他标准的参考文献。

IEC 61293:2019 establishes minimum requirements and general rules on marking electric equipment with ratings and other characteristics to enable the proper and safe selection and installation of electric equipment related to any supply of electricity.
The object of this document is to:
？ provide general requirements for the marking of the characteristics related to any supply system, such as voltage, current, frequency and power, without any restrictions;
？ provide technical committees with uniform methods for the marking of electrical ratings of products.
This document is primarily intended for application by technical committees when specifying minimum markings of ratings related to any electrical supply of equipment, sub-assemblies and components, but it is also for application by product manufacturers for marking their products.
This horizontal standard is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108.
One of the responsibilities of a technical committee is, wherever applicable, to make use of horizontal standards in the preparation of its publications. The contents of this horizontal standard will not apply unless specifically referred to or included in the relevant publications.
IEC 61293:2019 cancels and replaces the first edition published in 1994. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) its status as a basic safety publication has been removed, and it has become a horizontal publication in accordance with IEC Guide 108;
b) the scope is extended to include the applicability of this document to product manufacturers;
c) the addition of a provision that the visibility of the marking during normal operation should be considered;
d) more detailed requirements where equipment has a set or range of rated values for a given characteristic;
e) requirements regarding the provision of the markings also in the technical documentation have been added;
f) some notes have been converted to normative text;
g) normative references and references to other standards have been updated.
