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

2a and 2b.

— It was clarified that test 5 applies for both twin track conveyors and narrow span beam racking.

— It was clarified in Table 2, that test 4a,b should be conducted for a pallet without racking or stacking

but only on the top deck.
— The determination of nominal load was clarified in Table 3.

ISO 8611-2:2021(E)
Introduction

The forces to which pallets are exposed during use vary significantly. The test procedures described in

ISO 8611-1 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, it is possible that the results of tests do

not always reflect the user's perception of pallet performance in use.

It is possible that the nominal load does 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,
— ISO 8611-1 describes the test methods,

— this document describes the performance requirements and selection of tests, and

— ISO 8611-3 describes tests for determining maximum working loads for known payloads.

ISO 8611-1 and this document 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).

ISO 8611-1, this document 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 ISO 8611-1 and the

performance requirement is established from criteria in this document.

The following three types of intended use with specified support conditions are specified:

— 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 ISO 8611-3:2011, 4.2, 4.3 and 4.4) established

in ISO 8611-1 and this document. 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 ISO 8611-3:2011, Annex A 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 ISO 8611-1.

Introduction

The forces to which pallets are exposed during use vary significantly. The test procedures described in

ISO 8611-1 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,
— ISO 8611-1 describes the test methods,

— this part of ISO 8611 describes the performance requirements and selection of tests, and

— ISO 8611-3 describes tests for determining maximum working loads for known payloads.

ISO 8611-1 and this part of ISO 8611 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).

ISO 8611-1, this part of ISO 8611 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 ISO 8611-1 and the

performance requirement is established from criteria in this part of ISO 8611.

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 ISO 8611-1 and this part of ISO 8611. 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 ISO 8611-1.

DRAFT INTERNATIONAL STANDARD ISO/DIS 8611-2:2021(E)
Pallets for materials handling — Flat pallets —
Part 2:
Performance requirements and selection of tests
1 Scope

This part of ISO 8611 specifies the performance requirements to establish nominal loads for new flat

pallets.

It also specifies the tests required for new flat pallets in various handling environments and the

performance requirements for tests with payloads. 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.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 445 and the following apply.

3.1
breaking of one component

fracture of a structural element which significantly affects the strength, stiffness or functionality of

a pallet
3.2
concentrated load
load concentrated over an area of less than 50 % of the pallet top deck

maximum working load

greatest payload that a pallet is permitted to carry in a specific loading and support condition

Note 1 to entry: This varies according to the type, distribution, arrangement and means of stabilization of the

load and the system of support, and can be lower or higher than the nominal load (see, for example, Clauses 4 and

6 and see also ISO 8611-3).
