Organization: ASTM International
Publication Date: 1 May 2004
Status: inactive
Page Count: 4
ICS Code (Binders. Sealing materials): 91.100.50
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.
