Причина отмены

This test method covers the determination of the spectrophotometric diene value as a measure of the content of conjugated dienoic acids in dehydrated castor oil and its derivatives. Due to the high linoleic acid content in dehydrated castor oil and its derivatives, the absolute conjugated dienoic acid content cannot be determined by this test method.

Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in December 2003 in accordance with section 10.6.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by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.
