Standard Specification for HFC-227ea, 1,1,1,2,3,3,3-Heptafluoropropane (CF<inf>3</inf >CHFCF<inf>3</inf>)

ABSTRACT
This specification covers the requirements for 1,1,1,2,3,3,3-Heptafluoropropane (HFC-227ea) for use as a fire-fighting medium. However, this specification does not include the fire-fighting equipment or hardware that employs HFC-227ea, the conditions for employing such equipment, nor the storage or transportation of HFC-227ea. Material covered by this specification is of two types: Type I (mixtures of HFC-227ea and nitrogen) and Type II (HFC-227ea). Tests for purity, acidity, water content, fluoride ion content, suspended matter and sediment, nonvolatile residue, and fixed gases in the vapor phase shall be performed and shall conform to the requirements specified.
SCOPE
1.1 This specification covers requirements for HFC-227ea as a fire-fighting medium.  
1.2 This specification does not address the fire-fighting equipment or hardware that employs HFC-227ea or the conditions of employing such equipment (for example, handhelds, fixed installations, etc.).  
1.3 This specification does not address the storage or transportation of HFC-227ea. Storage, handling, and transportation issues may be addressed in future ASTM specifications.  
1.4 The values stated in both inch-pound and SI units are to be regarded separately as the standard. The values given in parentheses are for information only.  
1.5 The following safety hazards caveat pertains only to the test methods portion, Section 5, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Note 1.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
