ISO 12777-3:2002(E)
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 3.
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 part of ISO 12777 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 12777-3 was prepared by Technical Committee ISO/TC 51, Pallets for unit load method
of materials handling.
ISO 12777 consists of the following parts, under the general title Methods of test for pallet joints:
— Part 1: Determination of bending resistance of pallet nails, other dowel-type fasteners and staples
— Part 2: Determination of withdrawal and head pull-through resistance of pallet nails and staples
— Part 3: Determination of strength of pallet joints

ISO 12777-3:2002(E)
Introduction
This part of ISO 12777 was developed using methods that enable the user to select from a range of tests that best
fits the particular problem or area of the pallet under analysis. Some are suitable for routine quality control and some
are designed for laboratory use. Where characteristics of wood used in pallet joints are required then ISO 3133 and
related standards as given in clause 2 may be used.
In general the tests if used as routine quality control tests only require the measurement of ultimate load, while if the
tests are undertaken as prototype tests in a laboratory, then they also require measurement of deflection or distortion
in the joint plotted during the application of the load.

3 Terms and definitions
For the purposes of this part of ISO 12777, the terms and definitions given in ISO 445 apply.
4 Requirements for testing of joints
4.1 Fasteners
Prior to the assembly of any joints made with nails or staples, the nail bending strength shall be determined in
accordance with ISO 12777-1.
4.2 Timber
4.2.1 Selection
The timber shall either be selected in accordance with the pallet specification, or the test pieces shall be cut from
pallets manufactured for eventual mass production, or a laboratory type specimen made using clear straight grain
wood.
4.2.2 Comparative laboratory tests
For comparative tests on different types of nails or staples, these shall be driven into wood of carefully balanced
density and grain structure in laboratory prepared specimens.
NOTE Samples from the same board may achieve this balance of density and grain structure.
4.2.3 Joints
Joints shall be cut so that areas into which the fasteners are embedded are free from knots, local grain disturbance,
fissures and wane. Elsewhere the specimens shall be free from major defects which could lead to unrepresentative
failure in the timber.
4.2.4 Moisture content
4.2.4.1 General
For quality control tests the moisture content shall be as per pallet specification after noting the requirements for
tolerances of 5.2.
4.2.4.2 Method of measuring moisture content
For laboratory tests, the moisture content of the timber shall be determined using the “oven dry method” in
accordance with ISO 3130, and its density in accordance with ISO 3131.
NOTE Moisture content may be determined by electrical resistance as described in EN 13183-2.
4.2.4.3 Genus and species
For laboratory tests, the identity of the genus and where possible the species shall be confirmed by anatomical
examination. Where this cannot be done at the time of test, then a sample shall be retained for examination later.

4.2.5 Conditioning
◦ ◦
Timber shall be conditioned and tested at 23 C± 2 C, and as required in 5.1.1.
4.3 Wood-based sheet materials
4.3.1 Properties
Species mix, resin content, veneer or particle size, dimensional stability, density, moisture content and other
properties which will effect the test result shall be determined. These are typically available from the manufacturer or
supplier or specification of the product.
