BRIEF HISTORY
The IS0 Recommendation R 530, Dimensions for General Purpose Push-pull Single-
Pole Circuit-Breakers for Aircrafi, was drawn up by Technical Committee ISO/TC 20,
Aircraft, the Secretariat of which is held by the British Standards Institution (BSI).
Work on this question by the Technical Committee began in 1958 and led, in 1962, to
the adoption of a Draft IS0 Recommendation.
In September 1964, this Draft IS0 Recommendation (No. 744) was circulated to all
the IS0 Member Bodies for enquiry. It was approved by the following Member Bodies:
Argentina Germany Sweden
Belgium Israel Switzerland
Turkey
Canada Italy
Chile Japan U.A.R.
Czechoslovakia Netherlands United Kingdom
France Spain U.S.S.R.
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in December 1966, to accept it as an IS0 RECOMMENDATION.
