BRIEF HISTORY
The IS0 Recommendation R 457, Analysis of Soap. Determination of Chlorides, was
drawn up by Technical Committee ISO/TC 91, Surface Active Agents, the Secretariat of
which is held by the Association Française de Normalisation (AFNOR).
Work on this question by the Technical Committee began in 1961 and led, in 1962,
to the adoption of a Draft IS0 Recommendation.
In June 1963, this Draft IS0 Recommendation (No. 585) 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 Hungary Poland
Austria Italy Portugal
Canada Japan Romania
Chile Korea, Rep. of Spain
Colombia Morocco Switzerland
Czechoslovakia Netherlands United Kingdom
New Zealand Yugoslavia
France
Germany Norway
One Member Body opposed the approval of the Draft:
India.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in November 1965, to accept it as an IS0 RECOMMENDATION.
