WebbPVC - Inherent Viscosity - ASTM D1243. The PSL Rheotek RPV-2 determines the inherent viscosity (logarithmic viscosity number) of vinyl chloride polymers in dilute solution using glass capillary viscometers in accordance with ASTM D1243. The test method requires a 0.2% concentration. The dissolving solvent is Cyclohexanone. WebbThe viscosity of Newtonian fluids is affected by temperature, pressure, and, in the case of solutions and mixtures, by composition. The effect of pressure and temperature on the viscosity of gases is illustrated in Fig. 3.3 which shows the viscosity of carbon dioxide as a function of pressure and temperature (14).
