ASTM D6126/D6126M-11(2015)

Standard Specification for HFC-23 (Trifluoromethane, CHF<inf>3</inf>)

ABSTRACT
This specification covers the test methods and requirements for HFC-23 (trifluoromethane, CHF3) as a fire fighting medium. This specification, however, does not address the fire fighting equipment or hardware that employs HFC-23 or the conditions of employing such equipment (for example, handshields, fixed installations, etc.). It also does not address the storage or transportation of HFC-23. When analyzed by appropriate test methods, sampled specimens shall conform to requirements as to purity, acidity, water content, nonvolatile residue, and suspended matter or sediment.
SCOPE
1.1 This specification covers the requirements for HFC-23 as a fire fighting medium.  
1.2 This specification does not address the fire fighting equipment or hardware that employs HFC-23 or the conditions of employing such equipment (for example: handshields, fixed installations, etc.).  
1.3 This specification does not address the storage or transportation of HFC-23 Storage handling, and transportation issues are addressed in Practice D6127.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.5 The following safety hazards caveat pertains to the test methods portion, Section 6, 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 and health practices and determine the applicability of regulatory limitations prior to use.

3.1.1 halogenated hydrocarbon—the halogenated compound coding terminology system provides a convenient means to
reference halogenated hydrocarbons, ASRE 34. Halogenated hydrocarbons are saturated hydrocarbons in which one or more of the
hydrogen atoms have been replaced by atoms of the halogen series (fluorine, chlorine, bromine, and iodine). It is convention to
prefix the number with an abbreviation of the compound:
CFC = chlorofluorocarbon
HCFC = hydrochlorofluorocarbon
HFC = hydrofluorocarbon
FC = fluorocarbon
R = refrigerant
3.1.1.1 Discussion—
By definitions, the right most digit of the numbering system is the number of fluorine atoms.
3.1.1.2 Discussion—
The second digit from the right is the number of hydrogen atoms plus one (+1).
3.1.1.3 Discussion—
The third digit from the right is one less (-1) than number of carbon atoms in the compound (when this number is zero (0) it is
omitted from the number.
3.1.1.4 Discussion—
Unaccounted for valance requirements are assumed to be chlorine atoms.
