Adhesives for load-bearing timber structures. Test methods – Determination of the effects of wood shrinkage on the shear strength
| Published By | Publication Date | Number of Pages |
| BSI | 2013 | 18 |
This European Standard specifies a method for determining the influence of shear strength in crosswise gluing by wood shrinkage under drying conditions.
It is suitable for the following applications:
-
for assessing the compliance of adhesives with EN 301, EN 15425 and prEN 16254;
-
for assessing the suitability and quality of adhesives for load-bearing timber structures;
-
for determining if the adhesive is capable of withstanding stresses due to wood shrinkage without unacceptable loss of strength.
This test is intended primarily to obtain performance data for the classification of adhesives for load-bearing timber structures according to their suitability for use in defined climatic environments. This test is carried out on Norway spruce (Picea abies L.).
This method is not intended for use to provide numerical design data and does not necessarily represent the performance of the bonded member in service.
