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.
