BRIEF HISTORY
The IS0 Recommendation R 448, Marking of Industrial Gas Cylinders for the Identifica-
tion of the Content, was drawn up by Technical Committee ISO/TC 58, Gas Cylinders,
the Secretariat of which is held by the British Standards Institution (BSI).
Work on this question by the Technical Committee began in 1949 and led, in 1962,
to the adoption of a Draft IS0 Recommendation.
In March 1963, this Draft IS0 Recommendation (No. 574) was circulated to all the
IS0 Member Bodies for enquiry. It was approved by the following Member Bodies:
Argentina Greece Republic
Austria India of South Africa
Brazil Israel Romania
Canada Italy Spain
Chile Netherlands Sweden
Czechoslovakia Norway United Kingdom
Denmark U.S.A.
Five Member Bodies opposed the approval of the Draft:
Belgium
France
Germany
Japan
U.S.S.R.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in October 1965, to accept it as an IS0 RECOMMENDATION.
