This International Standard is one of a series giving specifications for fire extinguishing media in common use and which are in need of standardization for fire fighting purposes. These specifications are designe
16、d to establish that the medium in question has at least a minimum useful fire extinguishing capability and can therefore be reasonably sold for fire extinguishing purposes.

Halon 1301 is an odourless gas. A number of their other more important physical properties are
42、 given in table A.1. A.2 Electrical conductivity Halons 121 1 and 1301 have a very low electrical conductivity. In many cases they can be used to extinguish fires involving live electrical equipment, but this, to a significant extent, may de- pend on the circumstances, particularly the method of dis
43、charge. In case of doubt, reference should be made to the instructions on the fire extinguishing equipment to be used.
