1.1”This test method covers the measurement of apparent viscosity of roofing bitumen by means of a parallel plate plastometer. This test method is applicable for a viscosity range from 10² to 109 Pa”s [10³ to 1010 poises]. See Note 1.
Note 1:”This relatively simple test method of measuring viscosity uses predetermined, arbitrary shear stress levels. Since roofing bitumens are non-Newtonian, other viscosity test methods may give different results.
