Aerospace series - Rotorcraft life raft - Requirements, testing and marking
This document specifies minimum requirements for life rafts carried on helicopters operating in a hostile sea area or over very rough sea conditions. Life rafts covered by this document are for use by helicopter crew members and passengers in the event of a ditching or water impact.
They are intended either for integration into the helicopter, or stowed in the cabin before being manhandled out of the helicopter. This document does not cover air-drop life rafts.

Série aérospatiale - Radeaux de sauvetage de giravion - Exigences, essais et marquage
Le présent document spécifie les exigences minimales applicables aux radeaux de sauvetage transportés à bord des hélicoptères en cas d'opérations sur une zone maritime hostile ou lorsque la mer est très agitée. Les radeaux de sauvetage couverts par le présent document sont destinés à être utilisés par les membres d'équipage et par les passagers des hélicoptères en cas d'amerrissage forcé ou d'impact avec un plan d'eau.
Ils sont destinés à être intégrés dans l'hélicoptère, ou bien à être rangés dans la cabine avant d'être sortis à la main de l'hélicoptère. Le présent document ne concerne pas les radeaux de sauvetage largués.
Aeronavtika - Reševalni splav za rotoplane - Zahteve, preskušanje in označevanje
Ta dokument določa minimalne zahteve za reševalne splave, ki jih prevažajo helikopterji, za reševanje v neugodnih vremenskih razmerah ali na zelo razburkanem morju. Reševalni splavi, zajeti v tem dokumentu, so namenjeni članom posadke in potnikom helikopterja v primeru pristanka na vodi oziroma padca v vodo.
Namenjeni so za vgradnjo v helikopter ali pa so shranjeni v kabini, preden jih uporabnik ročno vzame iz helikopterja. Ta dokument ne zajema reševalnih splavov, ki se spustijo v vodo iz zraka.
