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.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 51, Pallets for unit load method of materials
handling.
This second edition cancels and replaces the first edition (ISO 18333:2002), which has been technically

Introduction
Efficient international transportation of products depends on both pallet strength and functionality,
or fit, to the material handling systems. Existing International Standards address issues of strength
and some issues regarding functionality of pallets. However, major issues related to the minimum
material quality and manufacturing and repair workmanship are not addressed in current International
Standards. These factors can significantly impact the efficiency of international unit load material
handling practices.
The purpose of this International Standard is to establish internationally recognized minimum
acceptable quality levels for wooden parts commonly used for the assembly of timber pallets. These
parts are stringers, stringerboards, blocks, and deckboards. The properties of these components affect
pallet performance.
There are four related International Standards:
— ISO 15629;
— ISO 18333;
— ISO 18334;
— ISO 18613.
