IEC 60136:2024主要适用于圆柱形换向器的电刷和刷座以及电动旋转机器的滑环。本文档的一些条款可以涵盖其他配置，例如扁平换向器或普通盘。它定义了电刷及其组件的尺寸及其公差: -刷块的尺寸(t，A，r)， -角度a和b， -倒角， -柔性（分流器）， -标准终端。 它还涵盖了主要尺寸的常规指定、电刷的标记以及电刷制造后鉴定的测试方法（IEC 60413涵盖的电刷级材料除外）。这第三版取消并取代了1986年出版的第二版和修正案1:19 95。本版构成技术修订版。 有关与上一版本相关的变更的完整列表，请参考文档的前言。

IEC 60136:2024 applies primarily to brushes and brush-holders for cylindrical commutators and slip rings for electrical rotating machines. Some clauses of this document may cover other configurations, such as flat commutators or plain disks. It defines the dimensions of brushes and their components, together with their tolerances:
- dimensions of brush block (t, a, r),
- angles α and β,
- chamfer,
- flexibles (shunts),
- standard terminals.
It also covers the conventional designation of principal dimensions, the marking of brushes and the testing methods for the qualification of brushes after their manufacturing (except the brush grade material, covered by IEC 60413). This third edition cancels and replaces the second edition published in 1986 and Amendment 1:1995. This edition constitutes a technical revision.
Please refer to the Foreword of the document for a comprehensive listing of the changes with respect to the previous edition.
