BRIEF HISTORY
The IS0 Recommendation R 850, Sodium nipolyphosphate for industrial use - Determination
of matter insoluble in water, 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 1960 and led, in 1966, to the
adoption of a Draft IS0 Recommendation.
In December 1966. this Draft IS0 Recommendation (No. 11 1 I) 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 :
Austria Israel South Africa, Rep. of
Belgium Italy Spain
Brazil Japan Switzerland
Bulgaria Korea, Dem. P.R. of Thailand
Chile
Korea, Rep. of Turkey
Czechoslovakia Morocco U.A.R.
France Netherlands United Kingdom
Germany
New Zealand U.S.S.R.
Hungary Poland
Yugoslavia
India Romania
No Member Body opposed the approval of the Draft.
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.
