ASTM D971 Standard Test Method for Interfacial Tension of Insulating Liquids Against Water by the Ring Method -- eLearning Course
About the Course
This course is based on ASTM D971 Standard Test Method for Interfacial Tension of Insulating Liquids Against Water by the Ring Method. This test method covers the measurement of the interfacial tension between insulating liquid that has a relative density (specific gravity) less than water and water, under non-equilibrium conditions.
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:
- Identify the key components of a manual interfacial tensiometer and its associated apparatus.
- Recognize the required purity standards for reagents and water used in the test.
- Describe the procedures for cleaning and preparing the apparatus and components used in interfacial tension testing.
- Describe the procedure for preparing test specimens and measuring interfacial tension with a tensiometer.
- Recall how to calculate interfacial tension and describe how to apply the correction factor.
- Identify the reporting requirements for ASTM D971.
