BRIEF HISTORY
The IS0 Recommendation R 241, Shanks for Turning and Planing Tools. Sections and Tole-
rances, was drawn up by Technical Committe lSO/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 1947, taking into account the
studies which had been made by the former International Federation of the National Standardizing
Associations (ISA), and led, in 1958, to the adoption of a Draft IS0 Recommendation.
In September 1959, this Draft IS0 Recommendation (No. 307) was submitted to all the IS0
Member Bodies for enquiry. It was approved, subject to some editorial amendments, by the follow-
ing Member Bodies :
Austria Hungary Portugal
Belgium India Romania
Burma Italy Sweden
Czechoslovakia Mexico United Kingdom
France Netherlands U. S. A.
Germany Pakistan U. S. S. R.
Greece Poland
One Member Body opposed the approval of the Draft: Switzerland.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in December 1961, to accept it as an IS0 RECOMMENDATION.
