Overview
ASTM D1257-22: Standard Specification for High-Gravity Glycerin defines the requirements and essential properties for high-gravity glycerin (minimum 98.7% by weight) used primarily in the manufacture of alkyd and other synthetic resins. Developed in accordance with World Trade Organization (WTO) technical standardization principles, this standard ensures that high-gravity glycerin meets stringent quality and consistency criteria necessary for industrial manufacturing processes.
High-gravity glycerin is a crucial raw material in various chemical industries, requiring precise quality assurance for effective resin synthesis and reliable product performance.
Key Topics
- Purity Specifications:
- Minimum 98.7% glycerin content by weight.
- Maximum values for sulfate ash content and acid value.
- Physical and Chemical Properties:
- Apparent specific gravity at defined temperatures.
- Maximum color value measured on the Pt-Co scale.
- Testing and Conformance:
- Determination of conformance with property limits using rounding-off practices as per ASTM E29.
- All property measurements must use SI units for standardization.
- Hazard and Safety Considerations:
- Users should reference the supplier's Material Safety Data Sheet (MSDS) for safe handling and potential hazards.
- Packaging Requirements:
- Packaging must conform to applicable transportation regulations or federal standards if specified.
Applications
ASTM D1257-22 is directly relevant to sectors involved in the production of:
- Alkyd Resins: Used in coatings, varnishes, and paints where controlled reactivity and purity of glycerin influence the performance, durability, and appearance of end products.
- Synthetic Resins: High-gravity glycerin ensures consistent polymerization during resin synthesis, supporting applications in adhesives, plastics, and specialty chemicals.
- Industrial Process Control: Establishing uniform criteria for glycerin quality assists manufacturers in quality control processes, supplier qualification, and regulatory compliance.
By following this specification, manufacturers and suppliers can:
- Ensure compatibility and consistency in resin production.
- Minimize quality-related production issues.
- Streamline procurement decisions by referring to globally recognized criteria.
Related Standards
Several standards and references are associated with ASTM D1257-22 to facilitate comprehensive quality management and compliance:
- ASTM E29: Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications.
- U.S. Federal Standard PPP-C-2020: Outlines requirements for the packaging of chemicals, liquids, dry materials, and pastes.
- ASTM D1258 (withdrawn): Previously covered test methods for high-gravity glycerin.
For ongoing compliance and best practices, reference to the latest versions of these standards and the supplier's documentation is recommended.
