(Test Method)Standard Test Method for Insoluble Matter in Rosin and Rosin Derivatives
Standard Test Method for Insoluble Matter in Rosin and Rosin Derivatives
SIGNIFICANCE AND USE
3.1 Rosin, particularly gum and wood rosin, occasionally contains small amounts of contamination such as sand, dirt or bark. Rosin derivatives occasionally contain traces of insoluble material as a result of the raw materials used in their production or they may be generated during the production process. In all instances the presence of such insoluble material should be minimal. This test method describes a rapid and reliable procedure for determining the amount of such insoluble matter. It is based on the knowledge that rosin and most of its derivatives are soluble in numerous organic solvents whereas most common contaminants are not. It is especially useful for internal quality control rather than sales specifications.
SCOPE
1.1 This test method covers the determination of the amount of insoluble matter in rosin and rosin derivatives as described in Terminology D804.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety problems, 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.
