ASTM WK96499

New Test Method for Standard Test Method for Recovered Carbon Black—Transmittance of Toluene Extract

1. Scope

This test method covers the measurement of the degree of toluene discoloration caused by recovered carbon black extractables and is useful in controlling the reaction processes for production of rCB.

Keywords

recovered carbon black; extractables; toluene discoloration

Rationale

Toluene Transmittance is currently performed according to a D24 standard for carbon black that does not reflect the specific conditions of a heterogeneous material like rCB. ASTM Committee D36 needs an own test method for this property. This proposal is based on D1618-23 but considers the specifics for rCB.
