scope:

1. Scope

1.1 This provisional specification covers requirements for CF3I (iodotrifluoromethane, CAS No. 2314-97-8) as a research and development agent for firefighting and explosion inertion/suppression. This provisional specification is not intended for large-scale commercial usage.

1.2 This provisional specification does not address firefighting equipment or hardware that employs CF3I or the conditions of employing such equipment (for example, portable extinguishers, fixed fire suppression systems, and explosion inerting systems, etc.).

1.3 This provisional specification does not address the storage or transportation of CF3I. The storage, handling, and transportation issues may be addressed in future ASTM specifications.

1.4 Iodotrifluoromethane has been found to be a cardiac sensitizer with a NOAEL (no observed adverse effect level) of 0.2 %. Therefore, sampling and other procedures should be performed only in areas with effective mechanical ventilation. Long-term exposures should be avoided pending the development of appropriate exposure standards.

1.5 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.

1.6 The following precautionary statement pertains only to the test method 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.
