Overview

ASTM D4995-10(2020) is a widely recognized international standard developed by ASTM International. It specifies requirements for three grades of 1,1,2-trichloro-1,2,2-trifluoroethane solvent, commonly referred to as trichlorotrifluoroethane or CFC-113. This solvent is primarily used in specialized cleaning processes, including electronic component cleaning and vapor degreasing.

The standard ensures product consistency by defining stringent physical and chemical properties such as boiling point, chemical purity, moisture content, chloride ions, specific aqueous conductance, acid number, and residue limits. By adhering to this standard, manufacturers and end-users can guarantee reliable performance and safety in high-precision industrial applications.

Key Topics

• Grades and Types:
  ASTM D4995-10(2020) classifies trichlorotrifluoroethane solvent into three types:

  • Type I: Electronic or ultra-clean grade, suitable for precision cleaning
  • Type II: Standard or vapor-degreasing grade, for general degreasing processes
  • Type IIA: General purpose grade, packaged in pressurized containers for versatile use

• Quality Control Properties:
  The standard establishes minimum and maximum limits for:

  • Boiling point (47.6°C ± 0.2°C)
  • Chemical purity (99.8-99.9% by weight)
  • Moisture content
  • Chloride ion content
  • Specific aqueous conductance (for monitoring ionic contamination)
  • Acid number (to ensure non-acidic solvent)
  • Residue limit (for minimal leftover after evaporation)

• Safety and Environmental Compliance:
  The standard emphasizes the importance of complying with safety, health, and environmental regulations, including those outlined by OSHA and EPA. Users are responsible for the safe handling and packaging of these solvents in accordance with DOT and other relevant guidelines.

Applications

Trichlorotrifluoroethane solvents covered under ASTM D4995-10(2020) are utilized in several critical industrial and electronic sectors:

• Electronics Manufacturing:

  • Cleaning of space vehicle components and precision assemblies
  • Maintenance of sensitive oxygen systems
  • Ultrasonic cleaning and testing of "assumed clean" components in cleanroom environments

• Vapor Degreasing:

  • Effective removal of organic residues and contaminants from metal, plastic, and glass substrates
  • Widely applied in aerospace, defense, and electronics industries for parts that require high cleanliness

• General Purpose Cleaning:

  • Type IIA grade is suitable for a broad range of industrial cleaning tasks, thanks to its convenient pressurized packaging

The standard facilitates quality assurance across supply chains, supporting processes where purity and material compatibility are critical to product reliability and performance.

Related Standards

A number of other ASTM and regulatory standards are referenced to ensure comprehensive quality and safety:

• ASTM D1078 – Distillation range of volatile organic liquids
• ASTM D2109 – Nonvolatile matter in halogenated organic solvents
• ASTM D3401 – Water content in halogenated organic solvents
• ASTM D3443 – Chloride determination in trichlorotrifluoroethane
• ASTM D3444 – Acid number of trichlorotrifluoroethane
• ASTM D3448 – Specific aqueous conductance measurement
• ASTM D6806 – Analysis of halogenated organic solvents by gas chromatography

Regulatory considerations also include:

• OSHA Hazard Communication (29 CFR 1910.1200)
• EPA Regulations on Ozone-Depleting Substances (40 CFR 82 Subpart E)
• DOT Hazardous Materials Regulations (49 CFR 100-199)

Compliance with ASTM D4995-10(2020) ensures that solvents used in sensitive or high-tech environments meet rigorous standards for performance, purity, and safety.
