ASTM D6126/D6126M-11e1

Standard Specification for HFC-23 (Trifluoromethane, CHF₃)

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 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 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.
