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)
