BRIEF HISTORY
The IS0 Recommendation R 759, Method for the determination of residue on evaporation on
a water bath, was drawn up by Technical Committee ISO/TC 47, Chemistry, the Secretariat of which
is held by the Ente Nazionale Italian0 di Unificazione (UNI).
Work on this question by the Technical Committee began in 1956 and led, in 1962, to the
adoption of a Draft IS0 Recommendation.
In November 1963, this Draft IS0 Recommendation (No. 659) 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 :
Hungary Portugal
Australia
Austria India Romania
Belgium Israel Spain
Chile Italy U.A.R.
Japan United Kingdom
Colombia
Korea, Rep. of U.S.S.R.
Czechoslovakia
France Netherlands Yugoslavia
Germany Poland
One Member Body opposed the approval of the Draft :
New Zealand
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in June 1968, to accept it as an IS0 RECOMMENDATION.
