Revision of D1618-23 Standard Test Method for Carbon Black Extractables—Transmittance of Toluene Extract

Rationale

Introduction of Method B in D1618. Method B is balloted as an alternative method for preparation of Toluene extract. A smaller pore size filter is required to provide adequate filtration for all materials currently approved for analysis by this test method. The proposal is to allow two different methods of preparation of Toluene extract (old Method A and new Method B). Numbering of footnotes will be updated.
