ASTM D 803 : 1997

1.1 These test methods cover the test procedures to be applied to whole tall oils or refined tall oils. Previous editions of these test methods have described test procedures that are used to test tall oil fatty acid, rosin, and other tall oil-derived products as well as test crude and refined tall oil. Consequently, these test methods are widely cited in reference books and industry literature for the testing of tall oil-derived products.

1.1.1 In this current revision, procedural details of some of the often-cited test methods have been removed and the test methods consolidated with other existing test methods. In such cases the consolidated methods, applicable to all tall oil-derived products, are referenced.

1.2 The procedures appear in the following order:

Physical Tests Sections Viscosity Brookfield Method (Preferred Method) 7 Bubble Time Method 8 Pour Point 9 Flash Point 10 Color 11 Moisture: Azeotropic Method (Preferred Method) 12 Karl Fischer 16 Ash 17 Chemical Analysis Acid Number 20 Saponification Number 21 Rosin Acids 22 Qualitative Test for Rosin 23 Unsaponifiable Matter 24 Fatty Acids 25
