(Specification)Standard Specification for Halon 1301, Bromotrifluoromethane (CF3Br)
Standard Specification for Halon 1301, Bromotrifluoromethane (CF<sub>3</sub>Br)
SCOPE
1.1 This specification covers the requirements for Halon 1301 as a fire-fighting medium.
1.2 This specification does not address the fire-fighting equipment or hardware that employs Halon 1301 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 1301. Storage, handling, and transportation issues are addressed in Practice D 5631.
1.4 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 4.3.
