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.

Introduction
International Standards giving a common classification with respect to durability classes for wood
adhesives allow considerable improvement in consumer protection in any future product liability
system with regard to properties guaranteed by the adhesive manufacturer.
The methods described in this document are suitable for the following and other applications:
— assessing the usability and quality of adhesives for wood and derived timber products;
— classifying these adhesives into the durability classes D1 to D4 of ISO 19210 (thermoplastic
adhesives) and C1 to C4 of EN 12765 (thermosetting adhesives);
— assessing effects on the bond strength resulting from the bonding conditions chosen, the various
conditioning sequences and the treatment of the test pieces before and after bonding.

SAFETY STATEMENT — Persons using this document should be familiar with the normal
laboratory practice, if applicable. This document does not purport to address all of the safety
problems, if any, associated with its use. It is the responsibility of the user to establish appropriate
safety and health practices and to ensure compliance with any regulatory conditions.
ENVIRONMENTAL STATEMENT — It is understood that some of the material permitted in
this document may have negative environmental impact. As technological advantages lead to
acceptable alternatives for these materials, they will be eliminated from this document to the
extent possible. At the end of the test, it is essential that the user of this document take care to
carry out an appropriate disposal of the wastes according to local regulation.
1 Scope
This document specifies tests for adhesives for wood and derived timber products for the assessment of
their resistance to hot and cold water. It can be used for the assessment of the strength of bonds with a
thin bond line. It does not apply to adhesives for structural use or to the manufacture of particleboards,
fibreboards and plywood. It does not replace tests on finished products.
