Plastikë - Përcaktimi i viskozitetit të polimerëve në tretje të holluar duke përdorur viskozimetra kapilarë - Pjesa 3:Polietilenët dhe polipropilenët (ISO 1628-3:2010)

Plastics - Determination of the viscosity of polymers in dilute solution using capillary viscometers - Part 3: Polyethylenes and polypropylenes (ISO 1628-3:2010)

Scope

ISO 1628-3:2010 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.
