3.1Committee 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.

3.2Committee 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.

1.1This 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.

1.2This 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.

1.3This 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.
