标准范围

IEC 60152:2021规定了三相交流系统中两个项目之间相位差的指定方法和规则。这些名称旨在应用于工业装置、设备和产品的技术文件中，也用于设备和产品的标记。IEC 60152:2021取消并取代了1963年出版的第一版。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)标题已更新，以反映文件的内容；b)用小时数识别导体的概念已被删除，因为该概念被认为已经过时并且存在其他识别导体的方法；c)介绍了小时数（时钟数）和相位差的定义。

IEC 60152:2021 specifies methods and rules for the designation of phase difference between two items in a three-phase AC system. The designations are intended to be applied in the technical documentation of industrial installations, equipment, and products, and also on markings of equipment and products.
IEC 60152:2021 cancels and replaces the first edition published in 1963. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the title has been updated to reflect the content of the document;
b) the concept of identifying conductors with hour number has been removed as the concept is considered out of date and other means for identifying conductors exists;
c) definition of hour number (clock number) and phase difference introduced.
