33、tatement Persons using this European Standard should be familiar with the normal laboratory practice, if applicable. This European Standard cannot address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health prac

34、tices and to ensure compliance with any regulatory conditions. Environmental statement It is understood that some of the material permitted in this European Standard may have negative environmental impact. As technological advantages lead to better alternatives for these materials, they will be elim

35、inated from this European Standard to the extent possible. At the end of the test, it is recommended that the user of this European Standard take care to carry out an appropriate disposal of the wastes, according to local regulation. EN 15416-1:2017 (E) DIN EN 15416-1:2017-05 6 1 Scope This European

36、 Standard specifies a method of determining the ability of adhesive bonds to resist long-term sustained load applied vertical to the glue lines. It is applicable to adhesives used in load-bearing timber structures. It is suitable for the following applications: a) for assessing the compliance of adh

37、esives according to EN 15425 and EN 16254; b) for assessing the suitability and quality of adhesives for load-bearing timber structures; c) for assessing the effect on the bond strength resulting from long-term sustained load at cyclic climate conditions. This method is intended primarily to obtain

38、performance data for the classification of adhesives for load bearing timber structures according to their suitability for use in defined climatic environments. This method is not intended to provide data for structural design, and does not necessarily represent the performance of the bonded member

41、ained load applied vertical to the glue lines at cyclic climate conditions. The test climate is at natural outdoor conditions in Europe between latitude 45 and 60. The loaded samples are protected with light penetrable covering (“Glass house”). 4 Apparatus 4.1 House for weather exposure The weather

42、exposure shall take place in a natural ventilated house covered with a light penetrating material where the air can circulate through openings along the floor and the roof. 4.2 Test jig The 10 samples, making a test set for each of the 3 duration of load times, shall be placed in a suitable test jig

43、 and loaded with a transverse tensile load according to 5.5.1. The test jigs shall enable a smooth loading of the test pieces. The individual samples shall be free to rotate to secure that the load will be applied 90 to the glue lines. NOTE Test jigs with a hanging dead load for the load application

44、 in combination with a vertical loading of the individual specimens using a principle as visualized in Figure 1 and Figure 2, has shown to be a suitable method.
