BRIEF HISTORY
The IS0 Recommendation R 523, Recommended Range of Outside Diameters ,for Milling
Cutters, was drawn up by Technical Committee ISO/TC 29, Small Tools, the Secretariat of which
is held by the Association Française de Normalisation (AFNOR).
Work on this question by the Technical Committee began in 1958 and led, in 1962, to the
adoption of a Draft IS0 Recommendation.
In April 1964, this Draft IS0 Recommendation (No. 669) was circulated to all the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial
nature, by the following Member Bodies :
Argentina France Spain
Australia Germany Sweden
Austria Hungary Switzerland
Belgium India Turkey
United Kingdom
Brazil Italy
Japan U.S.A.
Canada
Chile Korea, Rep. of U.S.S.R.
Colombia New Zealand Yugoslavia
Czechoslovakia Poland
Denmark Portugal
One Member Body opposed the approval of the Draft:
Netherlands.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in November 1966, to accept it as an IS0 RECOMMENDATION.
