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

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.

Methods of test for pallet joints —
Part 3:
Determination of strength of pallet joints
1 Scope
This part of ISO 12777 specifies methods of determining the resistance of pallet joints primarily to static load by
determining the strength and stiffness of nailed or stapled joints, wood to wood, wood to wood-based materials,
wood to plastics or plastics to plastics.
This part of ISO 12777 is applicable to joints with all types of nails up to 7mm in diameter (including plain shank,
helical, annular ring, barbed and twisted) and with staples.
