ASTM D4739 Standard Test Method for Base Number Determination by Potentiometric Hydrochloric Acid Titration -- eLearning Course
Price:
$174
About the Course
This test method covers a procedure for the determination of basic constituents in petroleum products and new and used lubricants. This test method resolves these constituents into groups having weak-base and strong-base ionization properties, provided the dissociation constants of the more strongly basic compounds are at least 1000 times than that of the next weaker groups. This test method covers base numbers up to 250.
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 apparatus and reagents used for determination of basic constituents in petroleum products and new and used lubricants.
- Recognize steps for preparation of electrodes and standardization of apparatus.
- Define steps for preparation of sample.
- Recall procedure for determination of base number and strong base number, including when to take readings.
- Recall steps for calculation of base number and strong base number.
- Identify reporting requirements as outlined for ASTM D4739.
