ASTM D7673/D7673M-21

Standard Specification for Halon 1211, Bromochlorodifluoromethane (CF<inf>2</inf>BrCl)

ABSTRACT
This specification covers the requirements for Halon 1211 as a fire-fighting medium. There are a number of limitations to this specification, such as the fire-fighting equipment or hardware that require the use of Halon 1211 and the storage or transportation of Halon 1211. Due to these limitations in this specification, storage, handling, and transportation issues may be addressed in future ASTM standards.
SCOPE
1.1 This specification covers the requirements for Halon 1211 as a fire-fighting medium.  
1.2 This specification does not address the fire-fighting equipment or hardware that employs Halon 1211 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 Halon 1211. Storage, handling, and transportation issues are addressed in Practice D7815.  
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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.5 The following safety hazards caveat pertains only 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 4.  
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.

hydrocarbons are acyclic saturated hydrocarbons in which one or more of the hydrogen atoms have been replaced by atoms from
the halogen series (that is, fluorine, chlorine, bromine, and iodine). By definition, the first dig
