Plastics — Determination of the viscosity of polymers in dilute solution using capillary viscometers...
This part of ISO 1628 specifies conditions for the determination of the reduced viscosity (also known as viscosity
number) and K-value of PVC resins. It is applicable to resins in powder form which consist of homopolymers of the
monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but
where vinyl chloride is the main constituent. The resins…
