5.2?This test method may not be suitable for rCB products containing either organic substances that decompose or oxidize only at temperatures of above 550?C or inorganic substances with decomposition temperatures ?550?C.

1.1?This test method provides a thermogravimetric (TGA) technique to determine the amounts of organic residue, overall carbon content, and ash content in recovered carbon black (rCB).

1.2?This test method uses previously calibrated, manual, or computer-assisted TGA instrumentation.

1.3?UnitsThe values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

1.4?This standard does not purport to address all of the safety concerns, if any, associated with its use.
