Overview
ASTM D4081-16(2023): Standard Specification for Drycleaning-Grade Perchloroethylene outlines the requirements for perchloroethylene used in the dry cleaning industry. Issued by ASTM International, this standard defines the necessary chemical and physical properties to ensure perchloroethylene’s suitability and safety for commercial dry cleaning operations. The specification establishes guidelines for purity, safety, and handling to meet both industry needs and regulatory compliance.
Key Topics
- Purity and Appearance: Drycleaning-grade perchloroethylene must be clear, free from suspended matter and undissolved water, and contain a minimum of 99.90% purity.
- Physical and Chemical Properties: The standard sets limits on water content, specific gravity, nonvolatile residue, assay percentage, acid acceptance, and boiling point range to guarantee performance and minimize potential machine corrosion.
- Safety and Environmental Responsibility: Users are reminded to develop proper safety, health, and environmental practices when handling this chemical, as the standard does not cover all possible hazards.
- Regulatory Compliance: The document references important regulations for labeling and shipping, including OSHA’s Hazard Communications (29 CFR 1910.1200) and the Department of Transportation's Hazardous Materials Regulations (49 CFR 100-199).
- Testing Methods: Specific ASTM methods are identified for testing the physical and chemical criteria, including tests for water content, specific gravity, acid acceptance, and nonvolatile residue.
Applications
Drycleaning-grade perchloroethylene is essential for commercial and industrial dry cleaning operations. The properties outlined in ASTM D4081-16(2023) are critical for:
- Ensuring Consistent Cleaning Quality: High-purity perchloroethylene delivers reliable results, minimizing residue or odors on textiles.
- Equipment Longevity and Maintenance: Limiting acids and impurities according to the specification reduces the potential for solvent-related corrosion and equipment damage.
- Safety and Hazard Management: Meeting precise specifications helps operators maintain safer working environments by controlling exposure to undesirable contaminants or by-products.
- Adherence to Regulations: Compliance with packaging and labeling rules as outlined in the standard helps businesses meet OSHA and DOT requirements, supporting safe transport and worker safety.
