Aircraft ground equipment — Upper deck catering vehicle — Functional requirements
ISO 27470:2011 specifies the minimum functional, performance and safety requirements for a catering vehicle capable of transporting and loading/unloading in-flight service (catering) equipment and supplies into or from the upper deck of very large capacity aircraft, as well as the main deck of these or other aircraft types. The intent of ISO 27470:2011 is not to specify equipment design, but rather to define minimum functional and performance requirements and highlight those criteria which are known to be essential to an efficient and safe operation on civil transport aircraft in the environment of international airports. ISO 27470:2011 specifies the worldwide requirements recognized by aircraft and vehicle manufacturers as well as airlines and catering agencies. In addition, it shall be applied with due reference to the national governmental regulations of the country where the vehicle is to be operated. The main though not exclusive areas in which such national regulations may apply are: a) general requirements applicable to road vehicles; b) sanitary requirements regarding design, cleaning and disinfection of vehicles used to carry food for human consumption; c) stability and other safety requirements applicable to elevating equipment carrying personnel in the elevated position. Nothing in ISO 27470:2011, however, shall be deemed to supersede any locally applicable law or regulation, unless a specific exemption has been obtained for this purpose from the appropriate Authority. Certain requirements of ISO 27470:2011 are specifically dictated by overwing access to doors of certain aircraft types, and may not apply to other aircraft types. However, the intent of ISO 27470:2011 is that any upper deck catering vehicle shall be capable of safely handling this specific situation.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 27470 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee

Introduction
This International Standard specifies the minimum functional, performance and safety requirements to be
taken into account by manufacturers for the design of catering vehicles intended to service the upper deck of
very large capacity aircraft. It identifies the various concerns to be taken into consideration to ensure vehicle
safety for operators and aircraft.
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 aircraft catering vehicles.
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.
