ASTM D5960-03(2023)

Overview

ASTM D5960-03(2023), Standard Specification for Technical Grade Ethylene Dichloride, establishes requirements for the quality and purity of technical grade ethylene dichloride (1,2-dichloroethane). Developed by ASTM International, this standard is widely recognized for promoting consistency and safety in the handling, packaging, and use of ethylene dichloride across global markets. The specification ensures that the product meets stringent criteria for composition, physical properties, and purity, supporting regulatory compliance and high performance in industrial applications.

Key Topics

• Product Purity: The specification defines minimum ethylene dichloride content and acceptable levels of impurities (such as water and acidity) to ensure product reliability.
• Physical Properties:
  • Color: Limits on the color (measured by the Platinum-Cobalt scale) help guarantee material quality and suitability for sensitive applications.
  • Specific Gravity: Strict requirements for specific gravity confirm the product’s consistency.
• Test Methods: The standard references precise ASTM test methods (such as D2108, D2111, D2989, D3401, and D6806) for verifying conformance to the specification. These methods ensure accuracy and reproducibility in measurement.
• Packaging and Labeling: Compliance with U.S. Department of Transportation (DOT) and Occupational Safety and Health Administration (OSHA) regulations is required for packaging, handling, and labeling, enhancing workplace safety and regulatory adherence.
• International Alignment: The standard is aligned with internationally recognized principles, ensuring its suitability for cross-border trade and compliance with World Trade Organization (WTO) Technical Barriers to Trade (TBT) Committee requirements.

Applications

Technical grade ethylene dichloride is extensively used in industries where quality control and regulatory compliance are crucial. Adhering to ASTM D5960-03(2023) ensures that manufacturers, suppliers, and users:

• Maintain Product Quality: By meeting strict specifications, producers can guarantee the performance and purity of ethylene dichloride used in chemical synthesis, particularly for vinyl chloride monomer production.
• Ensure Safety: Proper labeling and packaging in line with DOT and OSHA standards reduce risks during storage, handling, and transportation, thereby protecting workers and the environment.
• Facilitate Regulatory Compliance: Users can confidently comply with local, national, and international regulations, minimizing the risk of non-conformity.
• Support Consistent Industrial Processes: The defined specifications ensure consistent inputs for downstream processes, boosting operational efficiency and product reliability.

Industries benefiting from this standard include chemical manufacturing, pharmaceuticals, and other sectors relying on halogenated organic solvents.
