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 concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM D269-97(2020), Standard Test Method for Insoluble Matter in Rosin and Rosin Derivatives, establishes a reliable procedure for determining the amount of insoluble matter in rosin and its derivatives. Issued by ASTM International, this standard is essential for the quality assessment of natural and processed rosins, ensuring minimal contamination by insoluble substances such as sand, dirt, or bark. By leveraging the solubility characteristics of rosin and its derivatives in organic solvents, the method allows for straightforward differentiation and quantification of contaminants.
Key Topics
- Purpose: The test is designed to assess the cleanliness and purity of gum and wood rosin, as well as rosin derivatives, by identifying and quantifying insoluble material.
- Scope: Covers any rosin or rosin derivative, as detailed in ASTM D804, using organic solvents such as toluene, hexane, or mineral spirits to dissolve the sample while leaving insoluble materials.
- Methodology: Utilizes laboratory equipment including analytical balances, stainless steel mesh screens, filter apparatus, and forced draft ovens to accurately separate and measure insoluble content.
- Use of SI Units: All quantitative results are reported in standard SI units, affirming international applicability.
- Quality Control Focus: Especially valuable for internal process monitoring and quality assurance within manufacturing and processing operations, rather than for sales specifications.
- Safety and Environmental Practices: Users must establish appropriate safety and environmental measures when applying this standard.
Applications
The ASTM D269-97(2020) standard is widely used in a range of industries where rosin and its derivatives serve as key raw materials:
- Quality Assurance in Rosin Production: Ensures that final rosin products meet internal cleanliness standards, free from undue particulate contamination.
- Process Optimization: Assists manufacturers in monitoring and improving their purification process by detecting changes in the amount of insoluble material.
- Raw Material Assessment: Used to evaluate batches of natural or synthetic rosin before further processing or blending, both in gum and wood rosin industries.
- Product Consistency: Helps in maintaining consistent properties for rosin and rosin derivatives used in adhesives, inks, varnishes, and coatings.
- Regulatory Compliance: Supports due diligence for companies required to demonstrate quality control during external audits or in accordance with trade requirements.
Related Standards
For effective implementation and comprehensive understanding, the following related ASTM standards should be referred to:
- ASTM D804: Terminology Relating to Pine Chemicals, Including Tall Oil and Related Products - provides the foundational definitions for materials covered in ASTM D269.
- ASTM E11: Specification for Woven Wire Test Sieve Cloth and Test Sieves - specifies the requirements for mesh screens used in the test method to separate insoluble matter.
Practical Value
Implementing ASTM D269-97(2020) in industrial and laboratory settings ensures that rosin and rosin derivatives comply with quality benchmarks, reducing the risk of downstream processing issues. By routinely measuring insoluble matter, manufacturers can guarantee product integrity, enhance customer satisfaction, and improve operational efficiency. Using this internationally recognized standard strengthens a company’s quality management system and demonstrates commitment to industry best practices in rosin production and processing.
