Historical Standard: Standard Practice for Defining the Viscosity Characteristics of Hydraulic Fluids
ASTM D6080
Scope
1.1 This practice is applicable to all hydraulic fluids based either on petroleum, synthetic, or naturally-occurring base stocks. It is not intended for water-containing hydraulic fluids.
1.2 For determination of viscosities at low temperature, this practice uses millipascalsecond (mPa·s) as the unit of viscosity. For reference, 1 mPa·s is equivalent to 1 centipoise (cP). For determination of viscosities at high temperature, this practice uses millimetre squared per second (mm2/s) as the unit of kinematic viscosity. For reference, 1 mm2/s is equivalent to 1 centistoke (cSt).
1.3 This practice is applicable to fluids ranging in kinematic viscosity from about 4 to 150 mm2/s as measured at a reference temperature of 40°C and to temperatures from -50 to +16°C for a fluid viscosity of 750 mPa·s.
Note 1—Fluids of lesser or greater viscosity than the range described in are seldom used as hydraulic fluids. Any mathematical extrapolation of the system to either higher or lower viscosity grades may not be appropriate. Any need to expand the system should be evaluated on its own merit.
