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
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee
SC 9, Air cargo and ground equipment, in collaboration with the European Committee for Standardization
(CEN) Technical Committee CEN/TC 274, Aircraft ground support equipment, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

Introduction
The aim of this document is to deal with vibration as a hazard and to provide methods for the measurement
and reduction of vibration emission transmitted to the whole body of drivers of ground support equipment
(GSE) when driving. See EN 1032:2003+A1:2008 for determining whole body vibrations under stationary
operating conditions and hand-arm vibrations.
The results obtained can also be used to compare GSE of the same category or a given GSE when equipped
with different seats or tyres, etc.
Fitting different seats, changing the tyre specification, etc. can lead to different vibration values. Due to
the specific operation of GSE, however, EN 1032:2003+A1:2008 cannot be applied directly for whole body
vibration under driving conditions, and therefore, the preparation of this document for GSE has become
necessary.
This document cannot be used for field measurements to determine the daily exposure of the driver to
vibration.
This document is a type-C standard as stated in ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organisations, market surveillance etc.)
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
