WITHDRAWN RATIONALE
This guide covers the selection and application of procedures for testing fatty acids such as cottonseed, linseed, soybean, dehydrated castor, tall oil, etc. used in protective coatings.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this guide was withdrawn in December 2003 in accordance with section 10.6.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
