This document specifies a test method for comparing the compression shear strength of adhesive bonds and solid wood at 180 °C and a second elevated temperature. The maximum load of the test pieces after exposure to 180 °C and a specific elevated temperature for a specified duration of time is evaluated. It is applicable to adhesives used in load bearing timber structures and to other wood adhesives. This method is intended primarily to obtain data for the performance of wood adhesives at high temperatures. The result of this method (temperature class) can be used to classify the adhesive with respect to its performance in fire.
