ISO 26842-1:2020 PDF

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. NOTE When actual wood products are tested using this method, the test results might not be comparable because the test laboratory do not normally have had adequate control over the way the product was assembled. This document is not intended for use in the qualification of structural components.
