Standard Test Methods for Testing Tall Oil

Standard Details

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:	12
Insoluble Matter	13
Ash	14
Chemical Analysis
Acid Number	17
Saponification Number	18
Rosin Acids	19
Unsaponifiable Matter	20
Fatty Acids	21

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.
