Price: $174
About the Course

This course covers the test method that specifies a procedure for the determination of the kinematic viscosity, v, of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, n, can be obtained by multiplying the kinematic viscosity, v, by the density, p, of the liquid.

The course takes approximately 1 hour to complete and includes instructional video content, interactive knowledge checks, and a self-grading quiz. Downloadable resources include a pdf of the standard.

Learning Outcomes

By the end of this course, you will be able to:

  • Describe the viscometer, related components, and other apparatus used for the determination of the kinematic viscosity, ν, of liquid petroleum products, both transparent and opaque.
  • Recall the reagents, materials, and certified viscosity reference standards used for this test method.
  • Identify the calibration and verification specifications.
  • List the steps for the general procedure for kinematic viscosity.
  • Describe the procedures for transparent liquids, residual fuel oils, and opaque liquids.
  • List the steps for the cleaning of the viscometer.
  • Recall the calculations for kinematic and dynamic viscosity.
  • List the requirements for the expression of results and reporting.


Anyone who runs the D445 test method or who needs an understanding of the test method and how it is properly run.
