Energy efficiency of industrial trucks - Test methods - Part 1: General (ISO/DIS 23308-1:2024)

This document specifies general test criteria and requirements to measure the energy consumption for self-propelled industrial trucks (hereinafter referred to as trucks) during operation. For electric trucks, the efficiency of the battery and the battery charger is included.
The truck specific requirements in ISO 23308‑2 and ISO 23308‑3 take precedence over the respective requirements of ISO 23308‑1.
This document is applicable to the in-use phase of the product life cycle.
It applies to the following truck types according to ISO 5053‑1:
— counterbalance lift truck;
— articulated counterbalance lift truck;
— reach truck (with retractable mast or fork arm carriage);
— straddle truck;
— pallet-stacking truck;
— pallet truck;
— platform and stillage truck;
— pallet truck end controlled;
— order-picking truck;
— centre-controlled order-picking truck;
— towing, pushing tractor and burden carrier;
— towing and stacking tractor;
— side-loading truck (one side only);
— variable-reach container handler;
— counterbalance container handler;
— lateral-stacking truck (both sides);
— lateral-stacking truck (three sides);
— multi-directional lift truck.

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 on the ISO list of
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
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 110, Industrial trucks, Subcommittee SC 5,
Sustainability.
This second edition cancels and replaces the first edition (ISO 23308-1:2020), which has been technically
revised.
The main changes are as follows:
— in the Scope truck types according to ISO 5053-1 added and adapted;
— normative references updated;
— in the test report reference to the specific part of ISO 23308 added.
A list of all parts in the ISO 23308 can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.
