Procedure for Conversion to Saybolt UniversalViscosity5.1 Convert kinematic viscosities between 1.81 and 500mm2/s (cSt) at 100F, and between 1.77 and 139.8 mm2/s (cSt)at 210F, to equivalent Saybolt Universal seconds directly fromTable 1 (see Appendix X1, Example 1

18、).NOTE 2Obtain viscosities not listed, but which are within the rangegiven in Table 1, by linear interpolation (see Appendix X1, Example 2).5.2 Convert kinematic viscosities greater than the upperlimits of Table 1 at temperatures of 100 and 210F to SayboltUniversal viscosities as follows (see Append

21、 the relationship between Saybolt and kinematicviscosities is linear above 75 mm2/s (cSt), kinematic viscositiesabove this limit may be converted to Saybolt Universalviscosities at any temperature between 0 and 350F by use ofEq 1 (4.2), selecting the proper factor for B from Table 2 (seeAppendix X1,
