NB: 1% CONCENTRATION, NDJ-1 viscometer, spindle #4, 30 rpm.

OBSERVATION:

1. Viscosity of all grades drop as temperature rises.
2. In a temperature below 40 ℃. a rise in viscosity is observed on all grades except grade
   A as time becomes longer when temperature remains constant,
3. In a temperature above 60℃ ,a fall in viscosity is observed on all grades as time become
   longer when temperature remains constant.
