Overview
ASTM D5616-04(2022): Standard Specification for Reclaimed Trichloroethylene is an international standard developed by ASTM International. This specification defines the properties and performance criteria for reclaimed trichloroethylene (TCE) used primarily in noncritical industry applications, such as metal cleaning formulations. Developed in alignment with globally recognized standardization principles, ASTM D5616-04(2022) assists both purchasers and organizations establishing in-house trichloroethylene recovery or reclamation programs.
The standard classifies reclaimed TCE into three types according to purity and application suitability:
- Type I: Suitable for precision applications
- Type II: For less-demanding precision applications
- Type III: For general applications where all criteria may not be necessary
Key Topics
ASTM D5616-04(2022) covers:
- Three Grades of Reclaimed Trichloroethylene: Differentiated by specific gravity, purity, and contaminant limits for varying industrial requirements
- Physical and Chemical Properties: Specification of limits for water content, nonvolatile residue, acidity, color (Platinum-Cobalt scale), and acid acceptance
- Testing Methods: Reference to established ASTM test methods for consistent and reliable results, such as:
- D2111 for specific gravity
- D2109 for nonvolatile residue
- D3401/D1064 for water content
- D6806 for TCE assay and 1,1,1 trichloroethane content
- D2108 for color measurement
- D2942 for acid acceptance
- D2989 for acidity
- Regulatory Compliance: Packaging and labeling in accordance with US DOT and OSHA regulations to ensure safe handling and transportation
- Visual Appearance: Specification that all types must be clear and free from suspended matter
Applications
Reclaimed trichloroethylene conforming to ASTM D5616-04(2022) is widely used in various industries where noncritical cleaning and degreasing are required. Key application areas include:
- Metal Cleaning Formulations: Removal of oils, greases, and contaminants from metal parts in manufacturing and maintenance environments
- Solvent Recovery Programs: Use as a benchmark for organizations aiming to recycle or reclaim trichloroethylene on-site, minimizing costs and environmental impact
- General Industrial Cleaning: Suitable for less-demanding processes where high purity is not essential
This standard supports quality assurance in operations utilizing reclaimed solvents, ensuring consistent performance and compliance with regulatory frameworks.
