Scope
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??(70 and 210??. A special procedure for waxy products is indicated. Note 1??T 201 and ASTM D 445 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 D 2161. 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.
