ASTM D1585-96(2011)

Standard Test Methods for Fatty Acids Content of Naval Stores, Including Rosin, Tall Oil, and Related Products

SIGNIFICANCE AND USE
These test methods are designed to broaden the scope of the previous edition of these test methods by the inclusion of tall oil as a test material. Test Methods D803 currently includes methods for the determination of the rosin acid and fatty acid content of crude tall oil. Test Methods D803 references Test Method D1585.
Rosin and tall oil are composed primarily of rosin acids and fatty acids, and the measurement of these components is important in establishing the composition of these materials.
SCOPE
1.1 These test methods cover the determination of the fatty acids of naval stores, including rosin, tall oil, and related products.
1.2 These test methods may not be applicable to adducts or derivatives of rosin or other naval stores products.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
