Standard Test Method for Carbon Black—Solvent Extractables

Importancia y uso:

4.1 The carbon black extract test procedure provides a uniform and precise method for the gravimetric determination of organic-solvent extractables on carbon black. Accuracy and precision are acceptable for most specification or regulatory purposes, or both. However, carbon black with very low extract (less than 0.02 %) may require a more rigorous extraction procedure. The actual chemical composition of the extract can vary significantly with the type and origin of the carbon black.
