BRIEF HISTORY
The IS0 Recommendation R 347, Anchor Chains. End Shackles, was drawn up by Tech-
nical Committee ISO/TC 8, Shipbuilding Details, the Secretariat of which is held by the
Stichting Nederlands Normalisatie-instituut ("1).
Work on this question by the Technical Committee began in 1960, takin; into account the
stiidies which had been made hy the former International Federation of the National Standard-
izing Associations (ISA), and led, in 1961, to the adoption of a Draft IS0 Recommendation.
In June 1962, this Draft IS0 Recommendation (No. 509) 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 :
France New Zealand
Belgium
Burma Germany Poland
Chile Greece Spain
Czechoslovakia Japan Switzerland
Finland Netherlands Turkey
United Kingdom
Two Member Bodies opposed the approval of the Draft:
Italy, U.S.S.R.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in October 1963, to accept it as an IS0 RECOMMENDATION.
