BRIEF HISTORY
The IS0 Recommendation R 563, Knife sections of mower cutter bars, was drawn up by
Technical Committee ISO/TC 23, Agricultural machines, the Secretariat of which is held by
Repartiçao de Normalizaçao (IGPAI).
Work on this question by the Technical Committee began in 1952 and led, in 1961, to the
adoption of a Draft IS0 Recommendation.
In January 1965, this Draft IS0 Recommendation (No. 776) 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 Morocco Sweden
Austria Netherlands Switzerland
Chile Poland Turkey
France Portugal U.A.R.
Hungary Romania U.S.A.
Israel Spain U.S.S.R.
Seven Member Bodies opposed the approval of the Draft:
Canada Italy
Czechoslovakia Japan
Finland United Kingdom
Germany
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in April 1967, to accept it as an IS0 RECOMMENDATION.
