1、Designation: D1585 96 (Reapproved 2011)Standard Test Methods forFatty Acids Content of Naval Stores, Including Rosin, TallOil, and Related Products1This standard is issued under the fixed designation D1585; the number immediately following the designation indicates the year oforiginal adoption or, i
2、n the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover the determination of the fattyacids of naval stores, incl

Summary of Test Method3.1 The rosin acids content is determined using either themodified potentiometric Wolfe Method or the modified indica-tor
7、Wolfe Method described in Test Methods D1240. Rosinacids are calculated as abietic acid.3.2 The acid number is determined by either the potentio-metric or the indicator method in accordance with Test Meth-ods D465.3.3 The unsaponifiable matter is determined in accordancewith the methods described in
8、 Test Method D1065.3.4 The fatty acids are calculated by two methods.3.4.1 For materials with a fatty acid content less than 5 %,fatty acid content is calculated from the rosin acids content andthe acid number.3.4.2 For materials with a fatty acid content greater than5 %, fatty acid content is calcu
9、lated from the rosin acids andunsaponifiables content.3.5 The same method for end point detection, either poten-tiometric or indicator, should be used for acid number, unsa-ponifiables, and rosin acids content determination, in order toavoid slight variables that might occur.3.6 Since the fatty acid
10、s remaining in tall oil rosin, tall oil,and other naval stores products consist of oleic acid withvarying amounts of other saturated and unsaturated acids, it hasbecome customary to calculate and report the fatty acid contentas oleic acid.4. Significance and Use4.1 These test methods are designed to
