This part applies to portable fire extinguishers of which the maximum allowable pressure PS is lower than or equal to 30 bar and containing non-explosive, non-flammable, non-toxic and non-oxidising fluids.

This European Standard also applies to the metallic gas cartridge of a volume less than 0,12 l (see Annex E) and gives guidance for sound engineering practice for metallic gas cartridges equal to or greater than 0,12 l and less than 0,5 l, see Annex F.
