Energy efficiency of industrial trucks - Test methods - Part 4: Variable-reach rough-terrain trucks (ISO/DIS 23308-4:2025)
This document specifies the method of fuel consumption measurement for rough terrain- truck variable-reach trucks as defined in ISO 5053-1, herein after referred to as trucks. It does not apply to slewing trucks having a movement of more than 5° either side of the longitudinal axis.
This part is intended to be used in conjunction with ISO 23308-1. Where the requirements of this part differ from that in part 1, requirements in this part 4 will take precedence.

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).
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.

Introduction
The ISO 23308 series deals with energy efficiency of industrial trucks including batteries and 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 the industry and is
used to measure the energy consumption of electric industrial trucks and internal combustion (IC) industrial trucks.
The guideline is 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
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that
compliance with this document may involve the use of a patent.
ISO takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured ISO that he/she is willing to negotiate licences under reasonable
and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the
statement of the holder of this patent right is registered with ISO. Information may be obtained from the
patent database available at www.iso.org/patents.
