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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 20, Aircraft and space vehicles, Subcommittee
SC 9, Air cargo and ground equipment.
This second edition cancels and replaces the first edition (ISO 10327:1995), which has been technically
revised.

Introduction
The basic functions of main deck air cargo containers are
a) the unitization of cargo during ground handling and transportation, and
b) the restraint of their contents against accelerations encountered in flight.
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 safe, economical, and usable air
transport containers. Deviation from recommended criteria should only occur after careful consideration
and thorough service evaluation have shown alternate methods to provide an equivalent level of safety.
The requirements of this International Standard are expressed in the applicable SI units, with
approximate inch-pound units 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. Per
exception, the exact figures are those in inches for container base overall outside dimensions.
INTERNATIONAL STANDARD ISO 10327:2014(E)
Air cargo — Main deck containers — Design and testing
1 Scope
1.1 This International Standard covers the minimum design and operational testing requirements
for general purpose, base-restrained containers exclusively intended for the main or upper deck cargo
compartments of main line civil transport aircraft, capable of being used by either airlines or shippers
and requiring an airworthiness authority approval (certification).
NOTE 1 The metric equivalents for dimensions have been rounded up or down to the nearest millimetre, except
in critical dimensions. Masses have been rounded up to the nearest kilogram and forces have been rounded up to
the nearest 10 N.
NOTE 2 Though nothing technically prevents their being used for baggage, main deck containers are generally
used only for carriage of freight.
1.2 This International Standard does not cover the performance requirements and ultimate load testing
parameters for airworthiness authorities approval (certification), which are covered in ISO 21100 or, for
units approved prior to 2012, ISO 8097:2001. The design and operational testing requirements of this
International Standard are additional to the performance and certification testing requirements of these
International Standards.
1.3 This International Standard does not cover containers with an overall height of 1 625 mm (64 in)
or less, that can be loaded on the lower deck compartments of main line civil transport aircraft, which
are specified in ISO 6517, nor air-surface main deck containers, which are specified in ISO 4128 and
ISO 8323.
