ASTM D2764-20 PDF Download

ASTM D2764-20 is a standard test method used to determine the dimethylformamide-insoluble (DMF-I) content of tar and pitch. This test is important in evaluating and characterizing tars and pitches, as well as establishing the consistency of shipments or sources of supply. It provides a rapid and reasonably accurate measure of the toluene insoluble (TI) content of tar and pitch, which is determined by Test Method D4072.

The test method involves determining the amount of dimethylformamide-insoluble matter in the sample. It is an empirical test, meaning that strict adherence to all the procedure details is necessary. The test method is designed to provide a reliable measure of the DMF-I content in tar and pitch, thereby allowing for quality control and ensuring uniformity in the materials used.
