This Section of BS 5306 specifies requirements and gives recommendations for the design, installation, testing, maintenance and safety of halon 1301 total flooding fire extinguishing systems in building or plant, and the characteristics of halon 1301 and the types of fire for which it is a suitable extinguishing medium.
This standard covers only systems operating at 25 bar or 42 bar (at 20 °C) with nitrogen propellant; design data for other pressures and propellants are not available at this time.
This standard does not cover explosion suppression systems, systems in which halon is discharged to inert a flammable or explosive gas mixture, or small fixed fire extinguishers which are covered by BS 7327-1.
This Section of BS 5306 covers halon 1301 systems for use in buildings and other construction works. The systems are also widely used on ships and in aircraft, and while its requirements may apply in general for such applications, additional requirements may be necessary. Some information on marine applications is given in Appendix E.
NOTE 1 Unless otherwise specified in this standard all pressures are gauge pressures expressed in bars.
1 bar = 105 N/m2= 102kPa
NOTE 2 The titles of the publications referred to in this standard are listed on inside back cover.
