BS EN 17618 specifies a method for adhesives for wood and derived solid wood products for determining the shear strength and wood failure percentage of wood-to-wood adhesive bonds loaded in compression.
These parameters allow for the definition of different working properties of adhesives (e.g., final bond strength, pressing time, closed assembly time).
BS EN 17618 on the determination of shear strength by compressive loading:
The guidelines in BS EN 17618 for adhesives for wood and derived solid wood products for determining the shear strength and wood failure percentage of wood-to-wood adhesive bonds loaded in compression.
These parameters allow users to define different working properties of adhesives (e.g., final bond strength, pressing time, closed assembly time). Annex A gives the information required prior to testing.
BS EN 17618 proposes recommendations for the preparation of bonded assemblies, conditioning of test blocks, and preparation of specimens for determination of shear strength by compressive loading.
BS EN 17618 has facilitated and optimized most of the assembly requirements, especially since the adhesives used cure fairly quickly at room temperature.
