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

This document was prepared by Technical Committee ISO/TC 51, Pallets for unit load method of materials
handling.
This third edition cancels and replaces the second edition (ISO 8611-1:2011), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— The use of the deflection at the datum load was clarified.
— It was clarified that the average of the maximum deflections recorded for each replicate will need
to be reported.
— It was clarified that test 5 applies for both twin track conveyors and narrow span beam racking.
— It was clarified that the minimum of the ultimate load recorded for each replicate needs to be
reported.
— For test 11, the point where the leading edge of the pallet needs to touch the blade was changed from
100 to 250mm ± 25mm to 200mm ± 25mm.

Introduction
The forces to which pallets are exposed during use vary significantly. The test procedures described
in this part of ISO 8611 are approximate simulations of pallet use. These tests help the pallet designer
to establish an initial acceptable balance between the cost and the performance of a pallet design. It is
intended that all results of tests performed using this protocol be confirmed and verified using field
trials before publication of performance or the commercial implementation of a new pallet design.
The nominal load, determined according to this test protocol, does not represent a payload and cannot be
verified using field trials. The nominal load is a minimum payload level for use in determining maximum
working load according to the procedures in ISO 8611-3. The maximum working load can be verified for a
specified payload and intended use, using field trials. It is intended that the publication of the maximum
working load include a description of the payload and the intended modes of use of the pallet.
It is essential to exercise care when comparing the results of tests with historic experience using
existing pallet designs. User expectations of pallet performance vary. Some require greater and some
accept lower levels of performance. Users are accepting different levels of risk when using pallets.
Because of the varied performance expectations of pallet users, the results of tests might not always
reflect the user's perception of pallet performance in use.
The nominal load might not reflect users' perception of pallet performance because the nominal load
does not represent a payload. It is intended that maximum working loads be used to compare with the
historic performance of existing pallet designs.
Regarding the use of the ISO 8611 series,
— this part of ISO 8611 describes the test methods,
— ISO 8611-2 describes the performance requirements and selection of tests, and
— ISO 8611-3 describes tests for determining maximum working loads for known payloads.
This part of ISO 8611 and ISO 8611-2 are required for determining nominal load. The nominal load is the
lowest safe load value for the specified support conditions, independent of the type of load (excluding
concentrated loads).
This part of ISO 8611, ISO 8611-2 and ISO 8611-3 are required for determining maximum working loads
for known payloads.
The nominal load for the intended use is established by the selection of tests in this part of ISO 8611 and
the performance requirement is established from criteria in ISO 8611-2.
The following three types of intended use with specified support conditions are defined:
— handling of loaded pallets with racking and stacking;
— handling of loaded pallets without racking;
— handling of loaded pallets without racking or stacking.
To determine the maximum working load through testing given in ISO 8611-3, the deflection under
the known payload cannot exceed the limiting deflection (see 4.2, 4.3 and 4.4 of ISO 8611-3:2011)
established in this part of ISO 8611 and ISO 8611-2. The maximum working load is the greatest payload
that a pallet can be permitted to carry in a specific loading and support condition.
Guidance is given in Annex A of ISO 8611-3:2011 as to the general effect on performance of different
load types and stabilization methods. These can only give guidance as to the likely result from tests
with the known payload.
Other tests for durability evaluation are specified in this part of ISO 8611.

Pallets for materials handling — Flat pallets —
Part 1:
Test methods
1 Scope
This part of ISO 8611 specifies the test methods available for evaluating new flat pallets for materials
handling.
The test methods are split into groups for:
— nominal load testing;
— maximum working load testing;
— durability comparison testing.
It is not intended to apply to pallets with a fixed superstructure or a rigid, self-supporting container
that can be mechanically attached to the pallet and which contributes to the strength of the pallet.
NOTE Specific tests for determining load capacity do not replace the value of conducting field tests on
specific pallet designs.

Pallets selected for testing shall be measured to ensure that materials, construction and dimensions
conform to their associated written specification.
The mass and the material of each pallet shall be determined and recorded at the time of testing.
The moisture content of wooden pallets shall be measured and recorded in accordance with EN 13183-
2 at the time of testing.
The recorded deflection at each location in the test is the deflection at the end of the full test load

maximum deflections recorded for each replicate will need to be reported and used for further analysis.
Clause 9 gives further details on what should be recorded during testing and in the written report.
