SUPERSEDED (see Active link, below)
ASTM D465
1. Scope
1.1 These test methods are intended for determining the acid number of naval store products as defined in Terminology D804 including tall oil products, wood and gum rosin, and other related materials. These test methods may not be applicable to all modified rosin products. Two test methods are covered, as follows:
1.1.1 Potentiometric method (referee), and
1.1.2 Internal indicator method (alternate).
1.2 The potentiometric method is suitable for use with both light- and dark-colored products. It should be considered the referee method. The internal indicator method is suitable for use only with light- and medium-colored products with a Gardner color of less than 12. It should be considered the alternate method.
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.
