BRIEF HISTORY
The IS0 Recommendation R 866, Centre drills for centre holes without protecting chamfers -
Type A, 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 ths question by the Technical Committee began in 1960 and led, in 1965, to the
adoption of a Draft IS0 Recommendation.
In March 1966, this Draft IS0 Recommendation (No. 955) 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
India Portugal
Austria Israel Spain
Belgium Italy Sweden
Canada
Japan Switzerland
Chile Korea, Rep. of Turkey
Czechoslovakia Netherlands U.A.R.
France
New Zealand U.S.S.R.
Hungary Poland
Three Member Bodies opposed the approval of the Draft :
Ireland
United Kingdom
Yugoslavia
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in November 1968, to accept it as an IS0 RECOMMENDATION.
