1、Designation: D2161 10 (Reapproved 2016)Standard Practice forConversion of Kinematic Viscosity to Saybolt UniversalViscosity or to Saybolt Furol Viscosity1This standard is issued under the fixed designation D2161; the number immediately following the designation indicates the year oforiginal adoption

2、 or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1.

3、 Scope1.1 This practice2covers the conversion tables and equa-tions for converting kinematic viscosity in mm2/s at anytemperature to Saybolt Universal viscosity in Saybolt Univer-sal seconds (SUS) at the same temperature and for convertingkinematic viscosity in mm2/s at 122 F and 210 F (50 C and98.9

4、 C) to Saybolt Furol viscosity in Saybolt Furol seconds(SFS) at the same temperatures. Kinematic viscosity values arebased on water being 1.0034 mm2/s (cSt) at 68 F (20 C).NOTE 1Afundamental and preferred method for measuring kinematicviscosity is by use of kinematic viscometers as outlined in Test

5、MethodD445. It is recommended that kinematic viscosity be reported in millime-tres squared per second, instead of Saybolt Universal Seconds (SUS) orSaybolt Furol Seconds (SFS). This method is being retained for thepurpose of calculation of kinematic viscosities from SUS and SFS datathat appear in pa

6、st literature. One millimetre squared per second (mm2/s)equals one centistoke (cSt), which is another unit commonly found inolder literature.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are provided forreference information purposes only. The S

7、I unit of kinematicviscosity is mm2/s.1.2.1 ExceptionFahrenheit temperature units are used inthis practice because they are accepted by industry for the typeof legacy conversions described in this practice.1.3 This standard does not purport to address all of thesafety concerns, if any, associated wi

8、th its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Significance and Use4.1 At one time the petroleum industry relied on measuringkinem
