ASTM D1585-96

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

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.
