Rheological instability due to nonuniform distributions of widely different viscosity or molecular weight elements. ASTM International takes no position respecting the adtm of any patent rights asserted in connection with any item mentioned in this standard. The value for the instability will then be positive or negative.

ASTM D Flow Rates for Poly Vinyl Chloride – Instron

However, as a one-point measure of flow relative to shear rate, its one asstm is that the same PVC melt flow values sstm be obtained for materials having different processibility; the chance of this happening is minimized, however, if the compounds are similar in composition. The sensitivity of this test method makes it useful for correlating with processing conditions and as an aid in predicting changes in processing.
