Standard Test Methods for End Joints in Structural Wood Products
SIGNIFICANCE AND USE
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.
SCOPE
1.1 This standard provides test methods for evaluating the structural capacity and integrity of end joints in structural wood products.
1.2 Off-line test methods include: (1) Axial Tension, (2) Bending, and (3) Cyclic Delamination.
1.3 In-line test methods include: (1) Tension Proofload and (2) Bending Proofload.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
Adhesive bonded end joints are used in structural glued wood products. The bond performance of
these end joints is only one of several parameters that influence the in-service performance of these
products. Evaluating the performance of these end joints require specific tests.
The testing regimen, which may consist of one or more of the test methods specified in this
standard, is dependent on the type of product, the stage in the manufacturing of the product or
sub-components when the testing is to be performed, and the objective of the evaluation. Appendix
X1 – Appendix X7 provide an overview of considerations for developing a testing regimen.
