Plastics. Determination of the viscosity of polymers in dilute solution using capillary viscometers - Polyethylenes and polypropylenes Ingestion-build-47182 The design stage1 Scope This part of ISO 1628 defines particular conditions for determining the reduced viscosity (also known as viscosity number) and intrinsic viscosity of polyethylenes and polypropylenes at 135 C in dilute solution. The viscosity of polymer solutions may be affected by additives present in the sample. The value of a reduced viscosity determined by this method may therefore be unreliable if the sample contains fillers or other additives. NOTE
