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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at

a) fuel containers, except to the extent explicitly referred to in this document;
b) stationary, ship, railroad vehicle or aircraft dimethyl ether (DME) engine installations;
c) electronic fuel management;
d) refuelling receptacles.
NOTE 1 It is recognized that miscellaneous component properties not specifically addressed herein can be
examined for compliance with the criteria of any applicable part of the ISO 22760 series, including subjecting the
component to the appropriate functional tests.
NOTE 2 All pressures referred to in this document are gauge pressures unless otherwise specified.
