Omfang

This Aerospace Standard (AS) specifies the minimum design and performance criteria and testing methods of passive fire resistant containers (FRCs) used either: a. In those cargo compartments of civil transport aircraft where they constitute one means of complying with applicable airworthiness regulations, or b. On a voluntary basis, when deemed appropriate by operators to improve fire protection in aircraft cargo compartments where airworthiness regulations do not mandate their use. The fire resistant containers (FRCs) specified by this document are intended to be used to contain and restrain unitized cargo for loading into aircraft cargo compartments: a. Either class F cargo compartments according to CS-25 § 25.857(f) and AMC to CS-25.855 and 25.857 or FAA 14 CFR Part 25 § 25.857(f), in accordance with 1.1.a, or b. Class E aircraft cargo compartments according to CS-25 § 25.857(e), JAS Part 3, CCAR or 14 CFR Part 25 § 25.857(e), in accordance with 1.1.b. Containers are specified in this document only insofar as their flammability requirements and fire resistance performance are concerned. They are not otherwise specified in this document, but still require meeting the applicable general standards (see Section 3). NOTE: Though nothing prevents a fire resistant container (FRC) from being carried in a class C aircraft cargo compartment, it is not primarily intended for this use since its fire containment capability would be redundant with that of the aircraft's fire detection and suppression system. This document does not cover requirements for fire detection or suppression devices. The specified fire resistant containers (FRCs) are passive devices capable of containing a fire for the specified duration without the aid of detection/suppression devices. NOTE: Nothing, however, prevents additional use of self-contained fire detection or suppression devices within fire resistant containers (FRCs), but such active container devices are not specified herein and not part of the scope of this document. See 3.5.7. The containers specified in this document are to be designed and tested at both the detail- and assembly-levels to demonstrate performance. The use of fire resistant containers meeting the requirements of this document does not alone ensure flight safety: this document is based on the assumption that the fire resistant containers will be checked and loaded prior to aircraft loading in accordance with appropriate operating instructions, by competent, suitably trained, personnel as defined for example in ISO 9001:2008 sub-clause 6.2.2 (see [1] in Bibliography and Section 7).
