Standard Test Method for Apparent Viscosity (Flow) of Roofing Bitumens Using the Parallel Plate PlastometerMore info
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 pre-determined arbitrary shear stress levels. Since roofing bitumens are non-Newtonian, other viscosity test methods may give different results.
