About This Item
ASTM D6231/D6231M is the ASTM standard specification for HFC-125, identified as pentafluoroethane (C2HF5). It provides a technical reference for describing this refrigerant grade material in a consistent way, which supports procurement, quality control, and product evaluation. By defining the specification in a clear ASTM format, it helps buyers, suppliers, and users align on the expected material designation and documentation.
What is ASTM D6231/D6231M?
This standard is a specification focused on HFC-125, also known as pentafluoroethane and chemically identified as C2HF5. ASTM D6231/D6231M serves as a formal document for the material rather than a general guide, making it useful when a defined product description is needed. In practice, it helps establish a common basis for identifying the refrigerant and related requirements tied to commercial supply, inspection, and acceptance. The designation includes both inch-pound and metric formats.
Where is ASTM D6231/D6231M used?
This standard is commonly used wherever HFC-125 is specified, purchased, tested, or received as a defined chemical product. It is relevant in workflows that depend on consistent refrigerant identification, such as manufacturing, distribution, laboratory verification, and incoming material review. ASTM D6231/D6231M may also be used by technical teams and procurement groups that need a recognized specification for product comparison, documentation, and supplier communication. Its value is strongest when exact material naming matters.
Why is ASTM D6231/D6231M important?
ASTM D6231/D6231M matters because it gives users a recognized specification point for HFC-125, helping reduce confusion in ordering, acceptance, and quality control. A clear ASTM standard supports more consistent product evaluation and can improve confidence in documentation across the supply chain. For organizations handling this material, it may also help streamline compliance checks and internal review by providing a stable technical reference instead of relying on informal descriptions alone. That consistency is often important in regulated or specification-driven environments.
