Rubber, unvulcanized - Determinations using
a shearing-disc viscometer -
Part 2: Determination of pre-vulcanization
characteristic
(First revision)
(ISO 289-2:2016, IDT)
This part of ISO 289 specifies a method for determining the pre-vulcanization characteristics of
compounded rubber.
The pre-vulcanization characteristics determined by this method provide a means of estimating how
long compounded rubber can be maintained at high temperatures and remain processable
