Abstract
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.

The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods. The different types of errors were double amount of adhesives applied, two types of errors in cutting of the specimens and two types of eccentric loading during testing. The... (More)
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.

The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods. The different types of errors were double amount of adhesives applied, two types of errors in cutting of the specimens and two types of eccentric loading during testing. The maximum shear stress of the adhesive was used in determining whether the test methods are stable or not. The main conclusion of this thesis is that both test methods are unstable for the tested errors.
