ASTM D2171-01

1.1 This test method covers procedures for the determination of viscosity of asphalt (bitumen) by vacuum capillary viscometers at 60°C (140°F). It is applicable to materials having viscosities in the range from 0.0036 to over 20 000 Pa.s (0.036 to over 200 000 P).

Note 1 - This test method is suitable for use at other temperatures, but the precision is based on determinations on asphalt cements at 60°C (140°F).

1.2 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.
