TP-268 Carbon Residue Tester ASTM D189 (Conrad Method)

Applications

Under the test conditions specified in GB / T 268 (equivalent to ASTM D189), place the weighed sample in a crucible for decomposition distillation. The residue is heated strongly for a certain period of time to undergo cracking and coking reaction. After the specified heating time, put the crucible containing carbon residue in the dryer to cool and weigh, and calculate the carbon residue value (expressed by the mass percentage of the original sample).
