BS EN ISO 1628-5:2015 Plastics. Determination of the viscosity of polymers in dilute solution using capillary viscometers. Thermoplastic polyester (TP) homopolymers and copolymers
What is ISO 1628-5 - Viscosity of polymers using capillary viscometers about?
Both synthetic and natural polymers have essential uses in everyday life because of their broad spectrum of properties.
ISO 1628-5 specifies a method for the determination of the viscosity number of dilute solutions of TPs in certain specified solvents. The method applies to poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT), poly-(cyclohexylenedimethylene terephthalate) (PCT), and poly(ethylene naphthalate) (PEN), as well as to copolyesters and other polyesters, defined in ISO 77921 , that are soluble in one of the specified solvents under the specified conditions.
