ASTM D6541

This specification covers the requirements for HFC- 236fa HFC-236fa, 1,1,1,3,3,3-hexafluoropropane, (CF3CH 2CF3) as a fire-fighting medium. The materials are classified into two types: type I - mixtures of HFC-236fa and nitrogen, and type II - HFC-236fa. The purity, acidity, water content, non-volatile residue, fixed gases in the vapour phase, and suspended matter or sediment shall be tested to meet the requirements prescribed.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers the requirements for HFC-236fa as a fire-fighting medium.

1.2 This specification does not address the fire-fighting equipment or hardware that employs HFC-236fa or the conditions of employing such equipment (for example, hand-helds, fixed installations, and so forth).

1.3 This specification does not address the storage or transportation of HFC-236fa. Storage, handling, and transportation issues are addressed in Practice D 6427.

1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.5 The following safety hazards caveat pertains to the test methods portion, Section 6.1, 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. A specific warning statement is given in 4.3.
