SAE - AS6453A
Fire Containment Cover - Design, Performance, and Testing Requirements
|Publication Date:||1 December 2021|
This SAE Aerospace Standard (AS) specifies the minimum design and performance criteria and testing methods of fire containment covers (FCCs) 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 containment covers (FCCs) specified by this Standard are intended to be used to cover unitized cargo contained/restrained
a. Either class F cargo compartments according to CS-25 § 25.857(f), 14 CFR Part 25 § 25.857(f), and AMC to CS-25.855 and 25.857, AC 25.857-1, in accordance with 1.1 (a) above,
b. Or class B cargo compartments according to CS-25 § 25.857(b), JAS Part 3 or 14 CFR Part 25 § 25.857(b) with a Type Certification Basis prior to FAR 25-142 (CS-25 Amdt. 8), in accordance with 1.1 (b) above,
c. Or class E aircraft cargo compartments according to CS-25 § 25.857(e), JAS Part 3 or 14 CFR Part 25 § 25.857(e), in accordance with 1.1 (b) above.
NOTE 1: Though nothing prevents a fire containment cover (FCC) from being carried in a lower deck class C aircraft cargo compartment, it is not intended for this use since its fire containment capability would be redundant with that of the aircraft's fire detection and suppression system, which it could hamper.
The fire containment covers specified by this Standard may be of two types:
a. Type I: separate devices to be installed over a pallet's load below a net approved for this purpose, or
b. Type II: devices permanently attached to a pallet net approved for this purpose.
The unit load devices (pallet and net) used in conjunction with the fire containment cover are specified in this Standard only insofar as their flammability requirements are concerned. They are not otherwise specified in this Standard.
NOTE 2: See Bibliography for applicable ULD airworthiness approval and general design standards.
This Standard does not cover fire containment of loose baggage or loose cargo loaded in bulk cargo compartments.
This Standard does not cover requirements for fire detection or suppression devices. The specified fire containment covers (FCCs) are passive devices.
The use of fire containment covers meeting the requirements of this Standard does not alone ensure flight safety. This Standard is based on the assumption that the approved fire containment covers will be installed and checked prior to aircraft loading in accordance with appropriate operating instructions, by competent, suitably trained, personnel as defined for example in ISO 9001 (see Reference  in Bibliography and 9.3).
