This test method covers the determination of the hydroxyl content of castor oil, dehydrated castor oil, and their derivatives. This test method may also be used for other fatty products such as fatty alcohols, mono- and diglycerides, and hydroxystearic acid, but the precision will not necessarily be as indicated.

Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this test method was withdrawn in February 2007. This standard is being withdrawn without replacement due to its limited use by industry.
