Inherent / Intrinsic / Relative Viscosity ASTM D D D

The polymer is first weighed and then dissolved in an appropriate solvent. The ratio of the relative viscosity increment to the mass concentration of the polymer. The solution and viscometer are placed in a constant d403 water bath.

The liquid is then brought above the upper graduation mark on the viscometer.

ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity. Highly crystalline forms of PET that are not soluble in this solvent mixture will require a different procedure.
