Introduction
Mandatory requirements for recycling of packaging materials have led to an expansion of reuse, repair and
recycling of wooden pallets. This European Standard is intended to assist this process, in that, through its
implementation, the safety and longevity of repaired pallets will be maximised. The standard also refers particularly
to new pallet standards and prescriptive pallet specifications in wide use.
There is no requirement in this standard for pallet repairers to undertake tests, since, if guidance given in this
standard is followed and systematic repair and inspection systems are used, then a successful repair is recognised
to follow.
1 Scope
This European Standard specifies the maximum defects and damage allowed before a flat wooden pallet shall be
repaired, and defines the minimum repair criteria that shall be used.
This European Standard is applicable to wooden flat pallets repaired with wood based components.
NOTE The maximum allowed defects and damage for pallets are described in this standard and the annexes A to D show
examples of defects and damage which make the widely used pallets unacceptable for use. For other pallet types similar
criteria should be set up. The repair criteria for pool and rental pallets are controlled by their respective controlling
operators/owners, and may be subject to a licence.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).
EN 1087-1:1994, Particleboards – Determination of moisture resistance – Boil test.
EN ISO 445:1998, Pallets for materials handling – Vocabulary (ISO 445:1996).
ISO/DIS 15629:2000, Pallets for material handling – Quality of fasteners for assembly of new and repair of wooden
flat pallets.
3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN ISO 445:1998 (some of which
are repeated below for convenience) apply, together with the following:
3.1
board
top deck board, bottom deck board, or stringer board
3.2
deckboard
individual member of a top or bottom deck
3.3
bottom deck board
individual member of bottom deck

3.4
stringerboard
horizontal member linking the blocks and deckboards
3.5
stringer or bearer
continuous longitudinal member underneath the top deck or between the top and bottom decks, which provides
space for the entry of fork-lift forks and pallet-truck fingers.
4 Defects and damage criteria
4.1 Overriding criterion
The overriding criterion for an unacceptable pallet is if its condition is such that it cannot be regarded as safe and
that handling the pallet might be dangerous for persons or goods (as illustrated in annexes A to D).
4.2 Nail joint strength
Nail joint strength is particularly important for the performance of pallets.
4.3 Inspection
Inspection of a pallet shall take place before any handling, whether loaded or empty.
4.4 General conditions identifying an unacceptable pallet for use
The general conditions, which make a pallet unacceptable for use, are as follows:
a) one deckboard missing or broken, either obliquely or across;
b) either one block, stringer (bearer) or stringerboard missing or broken;
c) missing wood on deckboards to such an extent that on one deckboard, two or more nail shanks are visible, or
on more than two deckboards, one or more nail shanks are visible, or missing wood of more than ¼ of the
width of the board for ¼ length. Missing wood on a deckboard between the blocks of more than ¼ of the width
of the deckboard;
d) splits on deckboards of more than ½ of the width or the length of the deckboard, which cannot be securely
nailed;
e) wings on pallets may only have missing wood from inner deckboard ends for a maximum of 1/3 of projecting
wing length;
f) missing wood on blocks, stringers (bearers) or stringerboards, if more than one nail shank is visible at any one
joint;
g) depending on use, dirty or contaminated pallet. If any doubt exists as to the nature of the contamination, care
shall be taken in its identification and subsequent disposal;
h) older pallets with a combination of minor damage or loose joints and with a poor appearance may have a
combination of issues and be unacceptable when viewed as a whole;
i) pallets with bad workmanship. Pallets with materials or components that have been previously incorrectly
applied;
j) components affected by decay which could affect their mechanical properties;
k) Full width splits of any length in stringer (bearer) notches.

5 Repair
5.1 General
Components with unacceptable defects or damage shall be removed and replaced by new or reusable components
of one piece.
5.1.1 Blocks of particleboard
If blocks of particleboard are used they shall conform to EN 1087-1. The density of the particle board shall be more
than 580 kg per cubic metre.
5.1.2 Bottom deckboards
Bottom deckboards and the corners of the pallet shall be chamfered, if required.
5.1.3 Nail heads
Nail heads shall be countersunk so that the top of the head of the nail cannot be snagged above the surface.
5.2 Repair of pallets of known specification
Replacement components shall be from new or re-used materials. They shall be in accordance with the relevant
specifications of the pallet and its repair requirements in the relevant standards. Re-used components shall
conform to all the requirements of the new pallet component specifications. No missing wood or splits are allowed
in these re-used components. The nails used and the final assembled pallet shall meet the requirements of the
specifications for that pallet.
NOTE Repair requirements may differ from the new pallet specification. Details as agreed by contract.
Pallets which are unacceptable for use, shall be repaired or disposed of, and marking requirements met as defined
in 5.4.
5.3 Repair of pallets of unknown specification
If the specification is not known or no specification exists, the replacement components shall have the same
dimensions and quality as the removed components. Replacement components may be from new or re-used
materials. Components shall meet the conditions given in 5.3.3. Too many nail holes may weaken the component.
5.3.1 Dimensional tolerances
The general maximum permitted tolerances from basic dimensions for pallets of unknown specifications shall be as
in Table 1.
