ASTM C709-09

Standard Terminology Relating to Manufactured Carbon and Graphite (Withdrawn 2017)

WITHDRAWN RATIONALE
Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this terminology was withdrawn in December 2017. This standard is being withdrawn without replacement due to its limited use by industry.
