1.1 This practice covers kinematic viscosity-temperature equations and charts (see Figs. 1-3), which are a convenient means to ascertain the kinematic viscosity of a petroleum oil or liquid hydrocarbon at any temperature within a limited range, provided that the kinematic viscosities at two temperatures are known.

FIG. 1 Facsimile of Kinematic Viscosity-Temperature Chart I High Range (Temperature in degrees Celsius)

FIG. 2 Facsimile of Kinematic Viscosity-Temperature Chart I Medium Range (Temperature in degrees Celsius)

FIG. 3 Facsimile of Kinematic Viscosity-Temperature Chart I Low Range (Temperature in degrees Celsius)

1.2 The charts are designed to permit petroleum oil kinematic viscosity-temperature data to plot as a straight line. The charts have been derived from the equations shown in Section 5. The charts here presented provide a significant improvement in linearity over the charts previously available under Method D341 - 03. This increases the reliability of extrapolation to higher temperatures.

1.3 The values provided in SI units are to be regarded as standard.

1.3.1 Exception-The values given in parentheses are provided for information only.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
