1.1 This specification covers the requirements for HFC-23 as a fire fighting medium. 1.2 This specification does not address the fire fighting equipment or hardware that employs HFC-23 or the conditions of employing such equipment (for example: handshields, fixed installations, etc.). 1.3 This specification does not address the storage or transportation of HFC-23 Storage handling, and transportation issues are addressed in Practice D6127 . 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 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. 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.
