BRIEF HISTORY
The IS0 Recommendation R 254, Quality, Machining and Balancing of Transmission
Pulleys, was drawn up by Technical Committee ISO/TC 41. Pulleys and Belts (Including V-Belts),
the Secretariat of which is held by the Association Française de Normalisation (AFNOR).
Work on this question by the Technical Committee began in 1956 and led, in 1959, to the
adoption of a Draft IS0 Recommendation.
In May 1960, this Draft IS0 Reconimendation (No. 374) was circulated to all the IS0
Member Bodies for enquiry. It was approved by the following Member Bodies:
Australia Finland New Zealand
Argentina France Portugal
Belgium Germany Romania
Brazil Greece Spain
Chile India Sweden
Colombia Israel Switzerland
Czechoslovakia Japan United Kingdom
Denmark Netherlands U.S.S.R.
Two Member Bodies opposed the approval of the Draft:
Hungary, U.S.A.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Coun-
cil, which decided, in March 1962, to accept it as an IS0 RECOMMENDATION.
