This International Standard specifies a method for determining the apparent viscosity, at high shear, of poly(vinyl chloride) (PVC) pastes prepared from PVC paste polymers and plasticizers, using the Severs rheometer.
It applies in particular to “standard pastes” prepared in accordance with ISO4612 or ISO11468.
