ASTM D2416

Coking Value of Tar and Pitch (Modified Conradson)

Applicability: ASTM D2416 is applicable to determining the coking value of tar and pitch, a test method used to indicate the relative coke-forming potential of these materials. It is useful for characterizing tars and pitches, and for ensuring the uniformity of shipments or sources of supply. This standard is a modified Conradson carbon residue test.

Purpose: The purpose of ASTM D2416 is to provide a standardized test method for determining the coking value of tar and pitch. This test is used to evaluate the relative coke-forming tendencies of these materials, which is important for quality control and ensuring the uniformity of shipments. The test method involves heating a sample in a specialized apparatus at a high temperature for a set period and measuring the resulting coke residue.
