This document specifies a method for testing the strength of wood adhesives at 80 °C. NOTE The procedure described is based on a test developed in Germany known originally as the WATT '91 test. It uses the test piece described in ISO 19210.
Abstract
Overview
ISO 34257:2024 specifies a standardized method to determine the tensile strength of wood adhesive lap joints at an elevated temperature of 80 °C. Known as the WATT '91 test, this method evaluates adhesive performance under heat stress by testing bonded wood lap joints using procedures aligned with . Developed originally in Germany and now adopted internationally, this method provides a reliable metric for assessing the durability and strength of wood adhesives at elevated temperatures, supporting quality assurance and product development in woodworking and adhesive manufacturing.
