Work on this question by the Technical Committee began in 1957 and led, in 1966, to the
adoption of a Draft IS0 Recommendation.
In August 1966, this Draft 1SO Recommendation (No. 978) was circulated to all the IS0
Member Bodies for enquiry. it was approved, subject to a few modifications of an editorial nature,

Belgium India Spain
Brazil Ireland Sweden
Canada Israel Switzerland
Chile Japan Thailand
Czechoslovakia Korea, Rep. of Turkey
Denmark New Zealand U.A.R.
Finland Norway U.S.S.R.
Yugoslavia
France Poland
Germany Romania
Two Member Bodies opposed the approval of the Draft

U.S.A.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in October 1968, to accept it as an IS0 RECOMMENDATION.
