(Specification)Standard Specification for Halon 1211, Bromochlorodifluoromethane (CF2BrCl)
Standard Specification for Halon 1211, Bromochlorodifluoromethane (CF<sub>2</sub>BrCl)
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 may be addressed in future ASTM standards.
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 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. Specific hazards statements are given in 4.5.
