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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 8611-1 was prepared by Technical Committee ISO/TC 51, Pallets for unit load method of materials
handling.
This second edition cancels and replaces the first edition (ISO 8611-1:2004), which has been technically
revised.
ISO 8611 consists of the following parts, under the general title Pallets for materials handling — Flat pallets:
⎯ Part 1: Test methods
⎯ Part 2: Performance requirements and selection of tests
⎯ Part 3: Maximum working loads

ISO 8611-1:2011(E)
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.

19,8 % when conducting tests 1b and 7b.
6 Test load
A general value for the test load is not fixed. The test load for each test shall be determined in accordance
with ISO 8611-2.
The test load shall be applied with a testing machine, hydraulic or air pressure, or with dead load and shall
increase continuously or in steps to the failure (for determination of ultimate load) or up to the fixed value (for
qualification tests).
7 List of tests
Table 1 provides a matrix of the tests (in this part of ISO 8611) that shall be performed on flat pallets. Tests
numbered 1, 2, 3, 4, 5, 6 and 7 shall be performed with new pallets.

8.1.2 Procedure
8.1.2.1 In order to establish the weakest pallet support dimension, test one pallet across the length of the
pallet and then a second pallet across the width of the pallet. There is no requirement for further tests on the
stronger dimension unless the result is within 15 % of the weaker.
8.1.2.2 This having been established, place a fresh pallet across its weakest side, top deck uppermost,
on pallet supports positioned with their inside edges 75 mm from the outer edges of the pallet. The load
applicators shall be positioned at 0,18 L or 0,18 L , where measured as shown, where L or L is the
1 2 1 2
distance between the pallet supports (see Figure 1).

8.1.2.3 Load applicators and supports shall be flush with or project beyond the edges of the pallet. Edges
shall be relieved with (2 ± 1) mm radii. Where load applicators coincide with gaps between deckboards, in-fill
pieces of equal thickness to deckboards with 3 mm to 6 mm overall clearance on each shall be used. Place on
the pallet deck, the load applicators and the load board, then apply the rest of the test load.

The limiting condition of use for non-rackable and non-stackable single or double-deck pallets is the bending
of the pallet on fork arm supports under the top deck of the pallet.
8.2.2 Procedure
The forklifting test is shown schematically in Figure 2. The test method permits simulation of the forklifting
condition of use in each direction of pallet length and width. The supports shall conform to Figure 2. The
support distances may be either 570 mm or 690 mm (see Figure 2, footnote a). The shorter of the two
distances that occur during pallet use shall be used in the test. For pallets greater than 1 219 mm in length or
width, footnote a of Figure 2 may be adjusted according to the dimensions of the pallet.
Perform the test in both directions.
