5、Performance, and Testing Requirements RATIONALE This SAE Aerospace Standard (AS) specifies the design and performance criteria and testing methods applicable to fire containment covers intended to be used in conjunction with air cargo unit load devices in order to meet through oxygen depletion the f
6、ire containment regulations in certain civil transport aircraft cargo compartments. Throughout this Standard, the minimum essential criteria are identified by use of the key word “shall.” Recommended criteria are identified by use of the key word “should” and, while not mandatory, are considered to
7、be of primary importance in providing safe fire containment covers. Deviation from recommended criteria should only occur after careful consideration, extensive testing and thorough service evaluations have shown alternate methods to be satisfactory. The requirements of this Standard are expressed i
8、n the applicable SI units, with approximate inch-pound unit conversion between brackets. Where it is deemed necessary to use exact values, the SI units are to be used.

SCOPE 1.1 This SAE Aerospace Standard (AS), identical to ISO 14186, specifies the minimum design and performance criteria and testing methods of fire containment covers
12、 (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 air
13、worthiness regulations do not mandate their use. 1.2 The fire containment covers (FCCs) specified by this Standard are intended to be used to cover unitized cargo contained/restrained in an air cargo pallet and net assembly, for loading into aircraft main deck cargo compartments: a. either class F c
14、argo compartments according to CS-25 25.857(f) and AMC to CS-25.855 and 25.857, in accordance with 1.1 (a) above, b. or class B cargo compartments according to CS-25 25.857(b), JAS Part 3 or 14CFR Part 25 25.857(b), in accordance with 1.1 (b) above, c. or class E aircraft cargo compartments accordin
15、g to CS-25 25.857(e), JAS Part 3 or 14CFR 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 w
16、ould be redundant with that of the aircrafts fire containment and suppression system, which it could hamper. 1.3 The fire containment covers specified by this Standard may be of two types: a. Type I: separate devices to be installed over a pallets load below a net approved for this purpose, or b. Ty
17、pe II: devices permanently attached to a pallet net approved for this purpose. 1.4 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
18、 in this Standard. NOTE 2: See Bibliography for applicable ULD airworthiness approval and general design standards. 1.5 This Standard does not cover fire containment of loose baggage or loose cargo loaded in bulk cargo compartments. 1.6 This Standard does not cover requirements for fire detection or
19、 suppression devices. The specified fire containment covers (FCCs) are passive devices. 1.7 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 ins
20、talled and checked prior to aircraft loading in accordance with appropriate operating instructions, by competent, suitably trained, personnel as defined for example in ISO 9001: 2008, 6.2.2 (see Reference 7 in Bibliography and 9.3).

TERMS AND DEFINITIONS For the purpose of this Standard, the definitions of ISO 10254 and the following apply: 3.1 FIRE CONTAINMENT/FIRE CONTROL Ensuring that a fire does not grow to a
33、state where damage to the airplane or harm to passengers or crew occurs during the time for which the fire containment system is demonstrated to be effective. 3.2 FIRE CONTAINMENT COVER (FCC) Passive device used in conjunction with an air cargo pallet and net in order to contain a possible cargo fir
34、e beneath it for a rated period. Guidance addressing the use of FCCs is provided in airworthiness regulatory guidance as one of the allowable means of compliance with fire containment requirements in certain classes of aircraft cargo compartments. 3.3 ACTIVE UNIT LOAD DEVICE Unit load device incorpo
35、rating built-in fire detection and/or fire extinguishing systems. 3.4 PASSIVE UNIT LOAD DEVICE Unit load device or accessory thereto (e.g., FCC) that includes neither fire detection nor fire extinguishing systems, and ensures fire containment by its use of fire resistant or fire proof material and l
36、imiting the supply of air. 3.5 UNIT LOAD DEVICE (ULD) Device for grouping, transferring, and restraining cargo for transit. It may consist of a pallet with a net or it may be a container. 3.6 CLASS A FIRE Fires in ordinary combustible materials, such as wood, cloth, paper, rubber, and plastics for w
37、hich the quenching and cooling effects of quantities of water, or of solutions containing a large percentage of water, are of prime importance. 3.7 FIRE RESISTANT Grade designating components, equipment and structures capable of withstanding application of heat by a defined flame for 5 min, as oppos
38、ed to fire proof (see ISO 2685 and EUROCAE ED-14G sect. 26). 3.8 FIRE PROOF Grade designating components, equipment and structures capable of withstanding the application of heat by a defined flame for 15 minutes (see ISO 2685 and EUROCAE ED-14G sect. 26). 3.9 BURN LENGTH Distance from the original
39、edge to the farthest evidence of damage on a test specimen due to flame impingement, including areas of partial or complete consumption, charring or embrittlement, but not including areas sooted, stained, warped, or discolored, nor areas where material has shrunk or melted away from the heat source.

GENERAL REQUIREMENTS 4.1 Approval 4.1.1 The fire containment cover type design shall be approved on the basis of demonstration of compliance with the present Standard, and a Certificate of Conformity shall accordingly be delivered by the manufacturer. Where the fire conta
41、inment cover is intended to constitute a means of complying with applicable airworthiness regulations per 1.1(a) and 1.2(a), type approval should be sought from the airworthiness Authority concerned, who may include additional requirements. 4.1.2 The fire containment cover may be an entirely separat
42、e device (type I), or it may be attached to or integrated with an approved air cargo pallet net (type II). In the latter case, both sets of airworthiness approval requirements shall simultaneously be met, and no feature of either the cover or the net shall compromise an applicable requirement for th
43、e other function. The pallet net used in conjunction with the cover (type I) or attached to it (type II) shall be airworthiness approved under TSO/ETSO C90d, and meet the additional flammability requirements in 5.1.3. The TSO/ETSO C90d ultimate load requirements for the net and the flammability requ
44、irements are not required to be met simultaneously, because it is highly improbable that a cargo fire and maximum flight load condition would simultaneously occur. 4.2 Dimensions 4.2.1 The fire containment cover shall completely enclose one of the standard ULD contours in Annexes A to C, down to its
45、 base pallet edges but not covering its surface (see Note 4). NOTE 4: The absence of a floor covering requirement is based on the fact all known modern approved pallets have aluminum alloy base sheets sufficient to meet regulatory requirements CS-25/14CFR Part 25 Appendix F Part I (a) (2) (iii) by t
46、hemselves. FCCs built to the present Standard may not be suitable for pallets constructed of other materials. See 5.1.2: pallets not meeting this minimum performance requirement would at least require a cover with a bottom panel over the pallets surface, not specified in the present standard. NOTE 5
47、: Industry standard ULD contours, applicable to pallets, are defined in the IATA ULD Regulations (ULDR) standard specification 50/0 (see 10 in Bibliography). Where the FCC is intended and approved for one aircraft type only, the specific maximum ULD contour for that aircraft is to be used. In all ca
48、ses, maximum pallet load contour is 50 mm (2.0 inches) inside the maximum ULD contour on all four sides (see ISO 10046). NOTE 6: At the time of publication of this Standard, there are no known aircraft lower deck cargo compartments where fire containment covers are allowed means of meeting the regul
49、atory requirements. However, because pallets built-up to the lower deck contour can be carried on main deck, FCCs for this purpose may also be built to the lower deck P standard ULD contour (see Annex C). 4.2.2 The fire containment covers size shall provide sufficient clearance over the allowable contour to allow installation, but also to enable minimizing the risk of air entry at the base edge after installation (s
