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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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 .
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 , 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.
