【国外标准】 Standard Specification for Iodotrifluoromethane (CF3I)

1.1 This specification covers requirements for iodotrifluoromethane (CF3I, CAS No. 2314-97-8) as an agent for fire suppression. This specification is not intended for large-scale commercial usage.1.2 This specification does not address fire-fighting equipment or hardware that uses CF3I or the conditions of using such equipment (for example, portable extinguishers, fixed fire suppression systems, explosion inerting systems, and so forth).1.3 This 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 CF3I has been found to be a cardiac sensitizer with a no observed adverse effect level (NOAEL) 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 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.6 The following precautionary statement pertains only to the test method portion 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.1.7 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.
