Description / Abstract:
This test method covers the empirical procedures for determining
the Saybolt Universal or Saybolt Furol viscosities of petroleum
products at specified temperatures between 21 and 99°C (70 and
210°F). A special procedure for waxy products is indicated.
Note 1-T 201 and ASTM D445 are preferred for
the determination of kinematic viscosity. These methods require
smaller samples and less time, and provide greater accuracy.
Kinematic viscosities may be converted to Saybolt viscosities by
use of the tables in ASTM D2161. It is recommended that viscosity
indexes be calculated from kinematic rather than Saybolt
viscosities.
The values stated in SI units are to be regarded as the
standard. The values 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.
