Standard Test Methods for End Joints in Structural Wood Products

Importancia y uso:

4.1 These test methods are applicable to specimens with or without specific conditioning regimens. Tests are permitted to be performed on specimens that are not at moisture equilibrium, such as under production conditions in a plant, or on specimens that have been conditioned to specified moisture content or durability conditioning prior to testing.

4.2 These test methods can be used as follows:

4.2.1 To standardize the determination of strength properties for the material and joint being tested.

4.2.2 To investigate the effect of parameters that may influence the structural capacity of the joint, such as joint profile, adhesive type, moisture content, temperature, and strength-reducing characteristics in the assembly.

4.3 These test methods do not intend to address all possible exposure or performance expectations of end joints. The following are some performance characteristics not considered:

4.3.1 Long-term strength and permanence of the wood adhesive.

4.3.2 Time dependent mechanical properties of the joint.

4.3.3 Elevated temperature performance of the joint.
