ASTM D168 Standard Test Method for Coke Residue of Creosote
ASTM D168 Standard Test Method for Coke Residue of Creosote1. Scope1.1 This test method covers the determination of the coke residue (FIxed carbon) of creosote, coal tar, and creosote-coal tar solutions. As coal tars vary in their coke residue values, the method is therefore not a quantitative index ...
