ASTM D3205-86(1991)

Standard Test Method for Viscosity of Asphalt with Cone and Plate Viscometer (Withdrawn 2000)

SCOPE
1.1 This test method covers the determination of the viscosity of asphalt cements by means of a cone-plate viscometer. It is applicable to materials having viscosities in the range from 10  to 10   P (10  to 10  Pa[dot]s) and is therefore suitable for use at temperatures where viscosity is in the range indicated. The shear rate may vary between approximately 10   to 10  s   and the method is suitable for determination on materials having either Newtonian or non-Newtonian flow properties.  
1.2 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
