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.
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
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information

3.2
coloured veneer
wood veneer produced from either bleaching or dying procedure
3.3
laminated wood veneer
veneer sliced from wood flitch that is assembled from small pieces of wood strips with joints parallel to
grain
3.4
colour difference
difference between surface colour of the decorative veneer and the control colour of the sample veneer
colour or uneven colour of the surface in some case
Note 1 to entry: It does not include the colour difference between early wood and later wood, as well as the natural
grain colour difference on the wood surface itself.
4 Classifications
4.1 Classification according to the decorative veneer
a) natural wood veneered plywood;
b) coloured veneered plywood;
c) laminated wood veneered plywood;
d) multilaminar decorative veneered plywood.
4.2 Classification according to the face
a) single-faced decorative veneered plywood;
b) double-faced decorative veneered plywood.
4.3 Classification according to exposure classes
a) Exposure Class 1: for use in dry conditions;
b) Exposure Class 2: for use in tropical-dry/humid conditions.
5 Requirements and test methods
5.1 Panel dimensions and tolerances
5.1.1 General
Test methods and requirements as given in ISO 1954 and ISO 9426 apply to determine length, width,
squareness, and edge straightness of the panel.
