DIN EN 14256:2005-07

This European Standard describes a method for determining the ability of a test piece bonded with a thermoplastic adhesive, to support a given load for a specified time without fracture or excessive distortion, and specifies performance requirements for mean survival time and deflection in the test. It should be used in conjunction with EN 204 and EN 205 that describe durability classes and corresponding test methods for non-structural wood adhesives based on their ability to withstand various water treatments and relatively rapidly applied loads. The test described in this standard may be used to asses joints made with thin or thick gluelines, as defined in EN 205. NOTE The test described in this standard is not a mandatory requirement for the classification of adhesives into the classes D1, D2, D3 and D4 given in EN 204. It is an additional test that can be specified by a purchaser if required.
