BRIEF HISTORY
The IS0 Recommendation R 124, Determination of Total Solids of Latex, was drawn up
by Technical Committee ISO/TC 45, Rubber, the Secretariat of which is held by the British Stand-

adoption of a Draft IS0 Recommendation.
In March 1957, this Draft IS0 Recommendation (No. 145) was circulated to all the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial

India Spain

Canada Indonesia Sweden
Czechoslovakia Ireland Switzerland
Italy United Kingdom
Denmark
Finland Japan U.S.A.
Germany New Zealand U.S.S.R.
Greece Pakistan
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Coun-
