Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

ISO/FDIS 19281:2015(E)
Introduction
Fatal accidents have emphasized the risk to transport aircraft of uncontrolled fires occurring within
cargo, and evidence that the use of fire protecting devices can improve flight safety.
This International Standard specifies the design and performance criteria and testing methods for fire
resistant containers intended to be used in order to provide enhanced protection against cargo fires in
civil transport aircraft cargo compartments.
Throughout this International 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 be of primary importance in providing fire resistant containers meeting
the applicable regulatory requirements and ensuring effective protection against fires. Deviation from
recommended criteria should only occur after careful consideration, extensive testing, and thorough
service evaluation have shown alternate methods to be satisfactory.
The requirements of this International Standard are expressed in the applicable SI units, with
approximate inch-pound unit conversion between brackets for convenience in those countries using
that system. Where it is deemed necessary to use exact values, the SI unit ones are to be used.

Air cargo — Fire resistant containers — Design,
performance and testing requirements
1 Scope
This International Standard specifies the minimum design and performance criteria and testing
methods of passive fire resistant containers (FRCs) for carriage on aircraft main deck, to be used on
either of the following:
a) in those cargo compartments of civil transport aircraft where they constitute one means of
complying with applicable airworthiness regulations;
b) on a voluntary basis, when deemed appropriate by operators to improve fire protection in aircraft
cargo compartments where airworthiness regulations do not currently mandate their use.
The fire resistant containers (FRCs) specified by this International Standard are intended to be used
to contain and restrain unitized cargo for loading into either of the following aircraft main deck cargo
compartments:
a) Class B aircraft cargo compartments according to CS-25, CCAR-25, JAS Part 3 or 14 CFR Part 25
25.857 (b), in accordance a) or b) above;
b) Class E aircraft cargo compartments according to CS-25, CCAR-25, JAS Part 3 or 14 CFR Part 25
25.857 (e), in accordance with b) above;
c) Class F aircraft cargo compartments according to CS-25 § 25.857(f) and AMC to CS-25.855 and 25.857,
or 14CFR Part 25 § 25.857(f) and FAA Advisory Circular AC25.857-X, in accordance with a) above.
NOTE 1 Though nothing formally prevents a fire resistant container (FRC) 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. Consult
current regulatory guidance materials and aircraft type’s Weight and Balance Manual whenever available.
Containers are specified in this International Standard only insofar as their flammability requirements
and fire resistance performance are concerned. They are not otherwise specified in this International
