Scope

This part of ISO 1628 describes the conditions necessary for the determination of the viscosity number (also known as the reduced viscosity) and the relative viscosity of polycarbonates in dilute solution.It can be used for pure polycarbonates and blends with other polymers, as well as mixtures of both, with or without fillers, as defined in ISO 7391-1.
