BRIEF HISTORY
The IS0 Recommendation R 667, Determination of rate of cure of rubber compounds by the
shearing disk viscorneter, 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 by the Technical Committee began in 1948 and led, in 1962, to the
adoption of a Draft IS0 Recommendation.
In November 1963, this Draft IS0 Recommendation (No. 617) was circulated to ail the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial nature,
by the following Member Bodies :
Argentina Germany Poland
Australia Hungary Spain
Austria India Sweden
Israel Switzerland
Brazil
Italy United Kingdom
Canada
Japan U.S.S.R.
Chile
Korea, Rep. of Yugoslavia
Colombia
Czechoslovakia Netherlands
France New Zealand
One Member Body opposed the approval of the Draft :
U.S.A.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in February 1968, to accept it as an IS0 RECOMMENDATION.
