Pallets for materials handling - Flat pallets - Part 1: Test methods (ISO 8611-1:2011)

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.

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

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.

5 Precision and accuracy of tests and apparatus
Test apparatus shall satisfy the following requirements.

a) In the design of the test equipment, the tolerances on all dimensions shall be ±2 %.

b) The accuracy of measuring equipment for tests shall be ±0,5 mm.

c) The accuracy of positioning of every component, excluding the test load, shall be ±2 mm; measurement

gauges shall be positioned to ±4 mm.

d) The accuracy of positioning of the centre of application of test load (where used) shall be ±10 mm.

e) The total mass of the test load applied shall be within ±3 % of the prescribed value.

No part of any test rig shall distort an amount greater than ±3 mm when under maximum test load. Distortion

of the test rig shall be taken into account in measuring deflections of the pallet.

NOTE 1 Using heavy duty steel box sections in the construction of fixtures in tests 1 and 6 (see Table 1) normally

results in central distortions approaching the 3 mm given limit.

distance to change by 250 mm increments from 250 mm to 1 250 mm, each increment to within ±5 mm.

NOTE 2 Experience suggests that the interlaboratory test precision for conducting tests 1a and 7a is 16,7 %; and

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.

8.1.3 Measurements
8.1.3.1 Test 1a — Determination of bending strength

Place a load on the load board until breakage of one of the components of the pallet or until reaching an

excessive deflection or deformation. Record the ultimate load.
8.1.3.2 Test 1b — Determination of bending stiffness

Apply a datum load of (1,5 ± 0,5) % of the ultimate load determined in test 1a. Depending on the support

location, the deflection, y, shall be measured at points A [maximum of y at A (B ), A (B )A B ]:

a) after positioning of datum load;
b) immediately after full test load is applied;
c) at end of the full test load period;
d) after the relaxation period.
8.2 Test 2 — Forklifting tests
8.2.1 Purpose

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.
