Annotation of standard text ČSN EN 18070 (668533):

This document specifies a test method for comparing the compression shear strength of adhesive bonds in wood and solid wood after exposure to a target temperature for a specified duration of time.
This document is applicable to adhesives used in load bearing timber structures.
This document is not applicable to Epoxy- and two component Polyurethane-adhesives.
This method is intended to obtain data for the performance of wood adhesives at very high temperatures. The result of this comparison can be used to classify the adhesive with regard to the behaviour of load-bearing timber structures in fire
