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 ).

A list of all parts in the ISO 26842 series can be found on the ISO website.

1 Scope

This document gives guidelines to select, by means of delamination-resistance tests, adhesive/wood combinations for use in wood products placed in non-severe environments, in which the products are not exposed to extreme changes in temperature and humidity.

This document provides a series of exposure cycles at various temperature and humidity values to verify that the adhesive selected, or a product bonded with the adhesive, meets the necessary requirements for resistance to delamination.

This document is intended to help the user not only to select a suitable adhesive, but also to evaluate adhesives and adhesively bonded wood products.

This document is not intended for use in the qualification of structural components.
