This AS establishes minimum requirements for halocarbon clean agent hand-held fire extinguishers carried on board civil aircraft. The requirements include: design (cylinder, valve, gauge, mounting equipment), performance (firefighting effectiveness - hidden fire test, discharge test, type, etc.), environmental (ozone depleting/global warming potential, atmospheric life span), and occupant safety concerns (toxicology - seat fire test).

The purpose of this AS is to provide a technical basis for harmonized regulation of halocarbon clean agent handheld fire extinguishers across the international civil aviation community.
