Scope

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 10 ⁹ Pas (10³ to 10¹⁰ poises). See . Note 1This 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.

1.2 The values stated in SI units are regarded as standard. The inch-pound units given in parentheses are for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
