INTERNATIONAL ELECTROTECHNICAL COMMISSION
DEFINITIONS AND NOMENCLATURE FOR CARBON BRUSHES,
BRUSH-HOLDERS, COMMUTATORS AND SLIP-RINGS
FOREWORD
1)The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the
National Committees having a special interest therein are represented, express, as nearly as possible, an international
consensus of opinion on the subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the National Committees in that
sense.
3) In order to promote this inte rnational unification, the IEC expresses the wish that all National Committees having
as
yet no national rules, when preparing such rules, should use the IEC recommendations as the fundamental basis for these
rules in so far as national conditions will permit.
4)
The desirability is recognized of extending international agreement on these matters through an endeavour to harmonize
national standardization rules with these recommendations in so far as national conditions will permit. The National
Committees pledge their influence towards that end.
PREFACE
This Recommendation has been prepared by Sub-Committee 2F, Dimensions of Carbon Brushes,
Brush-holders, Commutators and Slip-rings, of IEC Technical Committee No. 2, Rotating Machinery.
Drafts of the Recommendation were discussed at meetings held in London in 1959, in New-Delhi
in 1960, in Bucharest in 1962, in Aix-les-Bains in 1964 and in Tokyo in 1965. As a result of this latter
meeting, a final draft was submitted to the National Committees for approval under the Six Months'
Rule in February 1966.
The following countries voted explicitly in favour of publication:
Australia Norway
Austria Romania
Belgium South Africa
Canada Sweden
Switzerland
Denmark
Finland Turkey
France Union of Soviet
Germany Socialist Republics

Electrographite
Consists of various forms of amorphous carbon converted during manufacture to artificial
graphite.
2.5 Metal-graphite
Consists of a mixture of metals and graphite.
2.6 Metal-impregnated graphite
