This part of ISO 1628 specifies a method for the determination of the viscosity number (also referred to as “reduced viscosityâ€?) of dilute solutions of thermoplastic polyesters (TPs) in certain specified solvents. The method is applicable 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 7792‑1 , that are soluble in one of the specified solvents under the specified conditions.

The viscosity number is determined by the general procedure specified in ISO 1628‑1 , observing the particular conditions specified in this part of ISO 1628 .

The determination of the viscosity number of a thermoplastic polyester provides a measure of the relative molecular mass of the polymer.
