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

Introduction
The ISO 23308 series deals with the energy efficiency of industrial trucks including batteries and
battery chargers.
ISO 23308-1 contains the procedures to determine the efficiency of trucks, traction batteries and
battery chargers. The other parts provide a specific test cycle for different truck types.
NOTE The test cycles are based on the VDI 2198 guideline. This guideline is widely accepted by industry and
is used to measure the energy consumption of electric industrial trucks and internal combustion (IC) industrial
trucks. The guideline has been in place since 1996 and it is used broadly. This approach allows the evaluation of
the energy efficiency of trucks by comparison.
The content of this document is of relevance for the following stakeholder groups:
— machine manufacturers (small, medium and large enterprises);
— market surveillance authorities;
— machine users (small, medium and large enterprises);
— service providers, e.g. for consulting activities.
The stakeholder groups above have been given the opportunity to participate at the drafting process of
this document. The machines concerned are indicated in the scope of this document.
