CEN/TC 193/SC 1/WG 13 - Fire behaviour

This document specifies a test method for determining the comparative compression shear strength of adhesive bonds and solid wood at both ambient temperature and elevated temperature. The maximum load of the test pieces at ambient temperature and after exposure to 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 performance data for the influence of elevated temperatures on the behaviour of adhesive bonds.
This method is not intended to provide data for structural design, and does not necessarily represent the performance of the bonded element in service.

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.
