标准范围

IEC 60773:2021适用于测量设计用于在规定测试条件下在换向和滑环机上运行的电刷的运行特性的测试方法。通过扩展，一些测试可能与用于电器的其他类型的滑动电触点相关。这第二版取消并取代了1983年出版的第一版。与上一版相比，此版本包括以下重大技术变更:-从实验室测试程序的角度对条款结构进行了修改。新的顺序如下:试验台规格、一般测试程序和每个操作特性的具体程序-增加了一项新条款，引入黑带测试来表征直流电机的电刷等级。

IEC 60773:2021 applies to test methods for the measurement of the operational characteristics of brushes designed to operate on commutating and slip ring machines under specified test conditions. By extension some tests may be relevant for other kinds of sliding electrical contacts for electrical appliances.
This second edition cancels and replaces the first edition published in 1983. This edition includes the following significant technical changes with respect to the previous edition:
- the clause structure has been modified on the view point of a laboratory testing procedure. The new sequence is as follows: test rig specification, general testing procedure, and specific procedure for each operational characteristic
- a new clause has been added to introduce the black-band test for the characterisation of the brush grades for DC machines.
