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.

This document applies to carbon brushes for electrical machinery. For the present, it applies only to carbon brushes for commutators and slip-rings in rotating machines. Terms and definitions are relative to the brush construction (references 100’s to 500’s and parts of 900’s) and to the markings when operating on a rotating machine (references 600’s to 800’s). By extension, terms and definitions may be relevant for any kind of sliding electrical contacts for electrical machinery.

This specification applies to rotating electrical machines with rated voltages (Un) from 5 kV to 24 kV inclusive and with rated output from 5 MVA upwards and from 5 MW upwards for motors Requirements for machines with rated voltage above 24 kV should remain the subject of individual agreement This specification is also applicable to machines with rated outputs between 1MVA( 1MW) and 5 MVA(5MW) and with rated voltages of 5 kV and above, provided its use has been agreed beforehand In the case of machines whose windings are cured in the stator, tests on the separate winding elements are not possible; for these machines the requirements in Part B apply. The test of the conductor lamination insulation must however be carried out in accordance with 23 of Part A of this standard
