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

Significance and Use

This is revision of the method for measuring rosin acids content combines the three major ways of determining the rosin acids content of naval stores products into a single method.

4.1.1 For materials containing less than 15 % rosin, the modified Glidden procedure has gained acceptance over the Herrlinger-Compeau. For materials containing more than 15 % rosin the modified Wolfe Method is preferred. The modified Wolfe and modified Glidden procedures differ only in their details. They have been combined here into a single procedure. This procedure can be run using either a potentiometer or an internal indicator to determine the end point of the titration. Use of a potentiometer is preferred and is the referee method. Use of an internal indicator is the principal alternative method. They will be referred to as the Potentiometric Method and the Internal Indicator Method to distinguish them from the Herrlinger-Compeau and Linder-Persson methods.

4.1.2 The Herrlinger-Compeau Method is limited in application to materials containing less than 15 % rosin. It is little used in the industry today. Much early work is based on this test method so it is included here to provide a historical basis for the overall test method.

4.1.3 The Linder-Persson Method is also little used in the industry today. It is applicable for measuring the rosin acids content of naval stores products containing greater than 60 % rosin. Like the Herrlinger-Compeau, it is included here to provide a historical basis for the test method. In those instances where they are used, the Herrlinger-Compeau and Linder-Persson methods are often in conjunction to cover the whole range of rosin content.


1.1 These test methods cover the determination of rosin acids in tall oil, tall oil fatty acid, tall oil rosin, and other naval stores products.

1.2 These test methods may not be applicable to adducts or derivatives of rosin, fatty acid, or other naval stores products.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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.
