BRIEF HISTORY
The IS0 Recommendation R 1 126, Determination of loss on heating of carbon blackfor the rubber
industry, was drawn up by Technical Committee ISO/TC 45, Rubber, the Secretariat of which is held by the
British Standards Institution (BSI).
Work on this question led to the adoption of a Draft IS0 Recommendation.
In September 1967, this Draft IS0 Recommendation (No. 1309) 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
Iran Sweden
Brazil Israel Switzerland
Canada Italy Thailand
Czechoslovakia Japan U.A.R.
France Netherlands United Kingdom
Germany New Zealand U.S.A.
Greece Poland
U.S.S.R.

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 1969, to accept it as an IS0 RECOMMENDATION.
