D36.10 - Recovered Carbon Black

SIGNIFICANCE AND USE
5.1 This test method is intended for use in quality control of production, for research and development purposes in which a compositional analysis or comparisons of different materials are needed.  
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.
SCOPE
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 Units-The 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. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
3.1 Committee D36 has concluded that typical carbon black characterization methods based on structure level and surface area measurements do not seem to correlate to in-rubber performance in an equal manner for Recovered Carbon Black products. Therefore, the committee does not recommend such test methods for predicting the applications performance of recovered carbon black products. The committee is open to new research that can contradict above statement.  
3.2 Committee D36 approved to recognize the standards in 2.1 as acceptable for use in the rCB industry until rCB statistical data is available that may suggest otherwise.
SCOPE
1.1 This guide includes a list of standards under jurisdiction of ASTM Committee D24 on Carbon Black; however, they can be applied for use in the rCB industry.  
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
